Series 5200D Diaphragm-Actuated Control Pinch Valve
Brand: Red Valve Company, IncRed Valve’s Series 5200D Diaphragm-Actuated Control Pinch Valve is available for customers who prefer diaphragm actuators.
Most significant is the valve’s ability to control in small diameter applications.
A diaphragm actuator offers a more responsive relationship between travel and air pressure since there is less friction and hysteresis than with piston actuators.
This results in more accurate response to the instrument signal and tighter control of the process fluid.
The Series 5200D Control Pinch Valve is designed with a heavy-duty, one-piece yoke.
This permits a wide array of accessories to be mounted directly and easily to the top works.
The Series 5200D Control Valve is available in stroke sizes up to 3".
For example, a 6" Control Valve with a 6" x 3" Cone Sleeve trim has 3" of stroke.
A direct mount or short yoke design is available to reduce overall valve height.
The simple construction of the diaphragm actuator makes it a highly cost-effective control valve.
