TESCOM 44-4000 dome loaded, spring biased regulator is designed for pressure tracking applications to maintain a constant differential pressure. Venting allows for pressure tracking increases and decreases.

High flow: Cv = 0.7 or 2.0 (optional) 
Piston sensed 
Adjustable bias pressure ranges are available 
Venting (captured) 
Compatible with Tescom’s Air Actuators and ER5000 Electropneumatic Controllers
