Direct Acting Solenoid Valves Have Higher AC & DC Pressure Ratings
ASCO introduced its 8262/8263 Series two-way and 8314 Series three-way direct acting solenoid valves with increased AC and DC pressure ratings and real-time online configuration and ordering. The two-way valves are ideal for applications in industrial and agricultural machinery, food products machinery, laundry and dishwashing appliances, and medical and analytical instruments. The three-way valves are ideal for process valve automation, fluid diversion, fluid mixing and piloting applications.
These valves are engineered with higher pressure ratings for AC and DC operation that enable original equipment manufacturers to achieve higher performance from their products. In addition, with the modular product architecture, a Web-based configuration tool, online ordering, and the ASCO Today guaranteed same-day shipping program, customers can rapidly configure and purchase an 8262/8263 or 8314 Series valve specifically for their application and receive it the next day.
The 8262/8263 Series valves come in brass and stainless steel constructions with 1/8-inch, 1/4-inch, and 3/8-inch pipe sizes and are used to control the flow of air, water, light oil, and specialty media such as cryogenic fluids, ammonia, oxygen, and liquid propane. The 8314 Series valves come in brass and stainless steel constructions with 1/8-inch and 1/4-inch pipe sizes and are used to control the flow of air, water, and light oil.
The online configuration tool allows a customer to quickly build a valve to meet a set of specific requirements. It then displays the list price, availability, 3D CAD drawings, and specifications for the configured product. The configurator generates an order code for the valve that permits an immediate online purchase, plus greatly simplifies the reordering process.
Pneumatic Solenoid Valve Designed For Flow Factors of 9.1-14 Cv
The Spartan Scientific Series 4700 valves are 2 way, 2 position, normally open or normally closed, pilot diaphragm operated solenoid valves specifically designed for high flow, high pressure applications such as condensation removal, carwashes, autoclaves and irrigation control. These valves, with orifice sizes of 20mm to 25mm and port sizes of ¾” and 1.0″ NPT are offered with a standard manual override. Depending on port size, the 4700 operates in a pressure range of 4.5 to 220 psi and has a flow factor of 9.1Cv to 14Cv. The encapsulated coil is a quick connect DIN 43650 Form “A” design and is compatible with air, oil, gas, water and fuel. The 4700 has an ambient temperature range of -15°C to +50°C.
Spartan Scientific is certified to ISO 9001 with design. Complete specifications and options can be found at www.spartanscientific.com
Gas Shut-Off Valves Have Compact Double Valve Footprint

ASCO Numatics introduced a new family of ASCO modular gas safety shut-off valves with a compact double valve footprint and the industry’s highest flow rates. The valves are ideal for boilers, furnaces, ovens, heating equipment, gas generators, and kilns used in commercial and industrial applications.
ASCO’s modular gas safety shut-off valves are available in two product families. The 8214(200) Series two-way normally closed solenoid valves can be used for fuel gases up to 5 psi. The V710(B)/AH(E) Series two-way normally closed electro-hydraulic actuated valves can be used with fuel gases up to 15 psi. This series is available with fast- and slow-opening constructions. Both product families come in 3/4” to 3” pipe sizes and have aluminum body constructions with pressure taps up and downstream.
Hazardous Environments Actuator Reduces Costs
PneuMagnetic, a manufacturer of valve operating solutions and solenoid valve actuators, announced an actuator design that achieves dramatic cost reductions in the installation of valves used in hazardous environments. The patented PneuMagnetic Actuator reduces installation cost by almost 50% in intrinsically safe (IS) installations, and by almost 20% in explosion proof (EX) installations.
The PneuMagnetic Actuator can reduce costs up to 50% in Hazardous Environments
The PneuMagnetic Actuator, a pneumatic magnetic replacement for OEM coils on direct acting solenoid valves, was designed by engineers because of the current of high costs, complexities and poor reliability of traditional valve actuators.
The PneuMagnetic Actuator’s U.S.-patented design is a complete, self-contained pneumatic magnetic device that provides the same powerful on/off magnetic field as the original coil. It is unique in five ways:
1) Unlike typical pneumatic actuators, its use is not restricted to factory-built pneumatic valves. Rather, it can be used as a direct drop-in replacement for the OEM coil on any direct acting solenoid valve. The PneuMagnetic Actuator is fully compatible with any original hermetically sealed valve.
2) The PneuMagnetic Actuator substantially reduces the cost of valve installations in hazardous environment. Valves converted to PneuMagnetic are operated by an inexpensive air pilot using a small diameter, flexible pneumatic line. No field wiring, conduit, or intrinsically safe (IS) barriers and no electricity at the valve are required.
3) The PneuMagnetic Actuator’s sealed design, combined with the fact that it works with hermetically sealed (packless) direct acting valves, allows it to offer extremely high reliability.
4) By essentially converting solenoid valves to pneumatic valves, PneuMagnetic technology dramatically expands the variety of valves available to the user.
5) The PneuMagnetic Actuator is less bulky than either pneumatic rotary actuators or pneumatic valves, reducing space requirements.
Speaking to the dramatic cost reduction inherent to PneuMagnetic’s solution, Altonji said “Direct acting solenoid valves require wiring and conduit installations that meet national and local codes. These requirements are typically several times the cost of the valve.”
Altonji noted that in hazardous installations including explosion proof (EX) and intrinsically safe (IS), this cost and complexity can be avoided if direct acting solenoid valves are converted to operate with the PneuMagnetic Actuator.
“Traditional electric installations require extensive material, labor, space, and time to install” said Altonji. “When compared with explosion proof (EX) or Intrinsic Barrier (IS) designs, the PneuMagnetic Actuator offers the lowest installed cost”.
The PneuMagnetic Actuator is available for use with a wide range of valves including ASCO, SMC USA and Parker-Skinner solenoid valves.
