Solenoid Valves for Pneumatic Actuators

The Assured Automation E and C series control valve is an inexpensive, simple and effective 3-way (E) or 3/4-way (C) solenoid/pilot valve. They are designed to mount directly to an NAMUR actuator thus reducing cost of tubing, fittings, brackets and labor.

The E series is only available in a 3-way configuration, which is most effective on spring return or fail-safe actuators where high speed open or close is not important. The C series is available in 3-way or 4-way configuration, which can be used on spring return or double acting actuators. Manual overrides (guarded-push to operate) are standard on all C series solenoid/pilot valves.

The B series is only available in a 3-way configuration, which is most effective on spring return or fail-safe actuators and is designed to mount to non-NAMUR actuators.

RetroLok Series Safety Lock Out Device

RetroLok® is a locking device that can be easily installed without modification to existing automation packages. This device allows quick visual determination from a distance of whether the quaterturn valve is locked open or closed by the locking pin flag.

Impact Spring Return Assist

The Impact spring assist is a pneumatic device whose purpose is to increase spring closing torque on spring return actuators. This is achieved by diverting air pressure from the inner chamber to the spring chambers so that in combination with the spring force an increase in the total closing torque of the actuator is achieved. Redirecting the air pressure into the spring chamber increases the spring end torque by 50% or more. The Impact can be utilized directly on site where operating conditions may occur that cause functional disorders or become a safety issue.

Some typical examples are given here:
• Actuatrors that are not achieving their published torque output can have the Impact field mounted to improve their reliability without having to replace them or stop the process.
• In situations where unexpected pressure drops occur, such as at the beginning of a day’s work or when additional accessories are added to the system, the Impact will keep the pressure level at its maximum and prevent the actuators from shifting their position.
• In many cases it is possible to substitute a smaller actuator with the Impact and achieve the torque output of a larger actuator.
• The Impact will increase the reliability and safety margin of existing actuators. The additional torque provided to existing actuators extend their life and reduce maintenance.
• The Impact is ideal for critical applications where quick-closing actuators are required.
• The Impact will help “self opening” valves keep their shut-off position.

FireChek® FC-4 Heat Activated Pneumatic Shut-off Valves

When FireChek® Senses excessive heat from a nearby fire,it immediately vents the pneumatic actuator and closes the actuator air supply line.

FireChek® triggers quickly,securing pneumatically operated process line valves. Because FireChek® responds to heat,not flame,it offers dramatically improved protection compared with conventional plastic tubing burn-through.It shuts off the air supply line to prevent plant air from feeding oxygen to a fire.
