February 5, 2009 by Pneumatics Editor
Filed under Valves
(Lexington, KY) With a width of only 17 or 21 millimeters, the universally applicable TC08 and TC15 valves provide a high flow rate of 0.8Cv in the TC08 and up to 1.5Cv in the TC15. A combination of in-line and manifoldable valves offer the user flexibility.
Individually or in a valve manifold, as a TC08 or TC15, the universally applicable valves from Rexroth.
The polymer valve body results in a light-weight package. The single valves can be flange mounted to any flat surface and the modular manifold system has room for up to 12 valve positions. The TC series is universally applicable, thanks to its electric connection options, choice of inch (1/8”and 1/4”NPT) or ISO-G (G1/8 and G1/4) ports, and they can even be used for vacuum applications.
A user-friendly, modular design with compact dimensions permits use in tight spaces. The valve manifold has an especially low height because it does not need subbases. Other features include easy exchange of valves without disassembling the manifold, and ability to have pressure zones via additional supply plates.
An Internet configurator is available to help configure factory assembled manifolds online, and provides a manifold part number and CAD drawing immediately.

LS04 Air Valve Series
February 5, 2009 by Pneumatics Editor
Filed under Valves
(Lexington, KY )– The new LS04 pneumatic valve series from Rexroth has dimensions of only ten millimeters width and a flow rate of 200 l/min (0.2Cv) up to a maximum of 330 l/min (0.33Cv).
The LS04 series comes in three different designs: a mini valve with optimized dimensions and a flow rate of 200 l/min (0.2Cv), a standard valve with 250 l/min (0.25Cv) and a valve manifold system with a flow rate of 330 l/min (0.33Cv). All valve variants are made of high strength polymer.
The LS04 features integrated push-in fittings for inch or metric tubing (working ports range from 1/8” to 1/4” and 4mm to 6mm). The electrical connections for the three types varies: the inline single valves are equipped with an M8 connector or standard connector and the valve terminal system has a multi-pin connection that can be used to control up to 24 coils. Users can implement mixed configurations with single and double solenoid or double 3/2-way valves.
Additionally, users can create different pressure zones or supply circuits in the valve terminal system using separators that can be positioned anywhere, making it possible to flexibly adapt the configuration to individual demands. The plug-in style valves can be exchanged without interfering with the electrical connections and the system can be expanded at a later point with two more valve positions.
The compact mini valve in the LS04 series covers the entire needs of modern valve technology for flows of up to 200 l/min (0.2Cv). As a 5/2-way valve, it takes care of the most common valve functions and can be operated with lubricated or non-lubricated compressed air. This also applies to the standard valve, particularly with the double 3/2 (split spool) function. Users in handling technology can also directly mount the LS04 on moving parts, thanks to its low weight. Even vacuum applications can be implemented with this valve, as it uses an external pilot air supply.

Valve Wide Open
February 5, 2009 by Pneumatics Editor
Filed under Valves
Dedham, Massachusetts – Driven by strong project activity, the worldwide control valve market experienced double-digit growth in 2006. The worldwide market for control valves is expected to grow at a compounded annual growth rate (CAGR) exceeding 5% over the next five years. The market, which approached $4 billion in 2006, is forecasted to exceed $5 billion in 2011, according to a new ARC Advisory Group study.
The global control valve market is in the midst of a phase of unprecedented growth due to booming Greenfield plants in developing countries and exploding investment in oil & gas exploration and production. “Much of the growth in the forecasted period will occur over the next two years as new construction projects in Asia soar and the oil & gas market boom continues. Following this increase, ARC Advisory Group expects a short-term dip in global control valve sales as the period of breakneck growth comes to an end. Long term year-on-year growth is then expected to taper to traditional levels,” according to Senior Analyst David Clayton, the principal author of ARC’s “Control Valve Worldwide Outlook” www.arcweb.com/res/cvap.
Wireless Technologies Help Digital Positioner Adoption
According to ARC, adoption of wireless technologies is a means of providing customers a cost effective solution to connecting production assets, like valves, to asset management and control systems, and it opens up many possibilities for improved control and optimized production by adding more field data that was previously too costly. Many of the leading control valve suppliers are adding wireless connectivity to their digital positioner products, because wireless not only allows manufacturers to connect valves to their systems, but also serves as a justification for them to replace older pneumatic positioners with digital positioners. Control valve suppliers are increasingly collaborating with manufacturers and wireless standards bodies, such as SP100 and the Wireless HART initiative, to develop standards-based wireless digital positioners that fulfill customer needs and expectations.
The Middle East Overtakes China
Though China still represents significant growth opportunities, the Middle East has quickly become the regional market offering control valve suppliers the greatest growth potential. Suppliers can expect increasing growth opportunities in the Middle East due to its high concentration of oil & gas activities.

Directional Bridge Circuit Takes Control
February 5, 2009 by Pneumatics Editor
Filed under Valves
The HydraForce SVCL and SPCL Series valves give integral piloting or load-signaling in a solenoid-operated on/off or proportional cartridge valve for an effcient, compact, and cost-effective method for directional control and load-holding applications.
A directional bridge circuit configuration using the SPCLxx-32 style valve omits the check valve in the integral sensing line. The load pressure then functions as a piloting signal. The SPCLxx-32 provides proportional control of the inlet flow to the motor. For the motor to operate, the pilot line of the SPCL supplies a pressure signal to open the counterbalance valve. This circuit configuration eliminates a return side directional element without loss of motor control. Return flow from the motor passes directly to the tank. This eliminates backpressure, reduces circuit components, improves overall efficiency, and significantly reduces cost versus a conventional directional control system.
In this example, the higher of two pressure signals functions as a load sensing pressure for the variable displacement pump, or for a pump unloading compensator when used with a fixed displacement pump because of the addition of the CV04 check valves.

New Dual-Function Solenoid Valve from HydraForce
February 5, 2009 by Pneumatics Editor
Filed under Valves
HydraForce SVRV10-26 dual-function cartridge valves combine the features of a normally-open solenoid valve with an integral non-adjustable relief valve. It is designed to be both cost-efficient and compact in hydraulic circuits incorporating both a bypass unloading function, as well as system pressure protection.
This valve can be used in a wide variety of system applications. In the de-energized position, pump flow is bypassed to the tank, allowing the motors to remain in the neutral condition. When the SVRV valve is energized, flow is directed to the motor, while the maximum motor torque is regulated by the setting of the SVRV’s integral relief valve.
The SVRV relief setting is fixed and non-adjustable. There are five standard pressure setting options, ranging from 104 bar (1500 psi) to 240 bar (3500 psi). Others can be made available upon OEM request. The SVRV10-26 is rated for flow up to 75 lpm (20 gpm) and pressure to 310 bar (4500 psi). Standard HydraForce 10-size “D” and “E” Series coils are used on the cartridge.
The new SVRV multi-function valve was developed to allow a smaller and lighter valve package, while simultaneously reducing the cost of both manifold machining and assembly by combining two functions into a single valve.
HydraForce is committed to continuing innovation in the design, manufacture, and application of hydraulic and electro-hydraulic control components and systems for the material handling and heavy-duty mobile equipment OEM industries.
