Tight control of your process requires certain components that ultimately maximize your machinery’s efficiency. Pneumatic tubing fittings come in many sizes and materials, but ultimately, they all work with your valves to operate your machinery to the fullest.

Heavy Duty Switches For Hydraulic & Pneumatic Systems
AMS Calibration has released the NOSHOK 400 series of heavy duty mechanical pressure switches.
Designed for use across a range of applications such as hydraulic and pneumatic systems, pumps and compressors and in power generation, the switches provide a stable switching point setting.
The 400 series switch converts pneumatic and hydraulic pressure into switching functions and is designed for applications that require accuracy under high loads.
The switching point is fully adjustable through an adjustment knob with the adjustment range, and includes a locking mechanism.
AMS Calibration’s switch is SPDT, and can be normally open (N.O.) or normally closed (N.C.) depending on the wiring.
The 400 Series Switch is fitted with DIN EN 175301-803 Form A connectors for fast and easy installation.
It is also available with an LED indicator on the plug for visual monitoring of the switch status, or an M12 x 1 (4-pin) electrical connection.
The switch features a repeatability of ±2% of full scale, 360° rotatable male connections, high loadability (shock 30g, vibration 10 g) and Hirschmann (DIN EN 175301-803 Form A) with optional 36″ cable.
AutomationDirect Extends Pneumatics Line

Filed under Featured, Fittings, Valves
The NITRA line of pneumatic components now includes additional fittings and valves for use with polyurethane and nylon tubing.
The ME and MS series fittings include two additional male straight and two male elbows with #10-32 thread. Added sizes include 5/32” and ¼” and are sold in packages of five starting at $4.25.
The MEL series includes two additional long male elbow fittings. The 5/32” and ¼” fittings feature #10-32 threads and prices start at $10.00 for a five-pack. The MSR series fittings are push-to-connect male straight round fittings available in ten sizes ranging from 5/32” to ¼” and 4mm to 6mm. These fittings feature a nickel-plated brass body with an internal hex socket, stainless steel gripping claws and pre-applied Teflon thread sealant. Prices start at $4.00 for a pack of five.
The HVU series of three-way hand valves is available in seven sizes ranging from ¼” to ½” and 6mm to 12mm; the valve blocks upstream pressure when closed and vents downstream pressure. Sold in packs of two, prices start at $12.75.
CVU series union check valves have been added ranging from 5/32” to 3/8” and 6mm to 8mm sizes. The check valves allow air flow in one direction and block air flow in the reverse direction. Sold in packages of five, prices start at $28.75. Stop valves are now available in sizes ranging from 5/32” to ½” and 6mm to 12mm diameters. Designed to block upstream air pressure when the downstream tube is removed, union stop valves are sold in packages of five starting at $26.75. A pneumatic tubing cutter designed for use with 1/8” to ½” and 4mm to 12mm flexible plastic tubing is available for $4.25.

Electro-pneumatic Positioners
July 18, 2009 by Pneumatics Editor
Filed under Actuators, Featured, Fittings
The Series 6A line of Intelligent Electro-Pneumatic Positioners offer precise flow control and digital communication. For use with either double or single acting pneumatic actuators, the positioners can accept an analog 4-20 mA input or BUS intelligent HART, FOUNDATION Fieldbus™ or PROFIBUS PA input. Both waterproof (NEMA 4, 4X/IP66) and explosion proof (NEMA 4, 4X, 7 and 9) enclosures are offered. A waterproof stainless steel enclosure is available upon request.
Piezo valve technology controls the air supply, producing zero bleed during steady state and minimal consumption during operation. An LCD display provides visual confirmation of valve position in precise one-degree increments. Auto Calibration quickly determines the position of the travel limit stops, then measures and records the parameters for both the open and closed positions. The settings are then stored. Online Adaptive Control continually optimizes control parameters and travel times in response to changes in line pressure.
