● Manual digital display preset function, allowing presetting of maximum flow rate; 

Equipped with multi-angle observation windows.

● Universal M30X1.5 threaded connection port can be connected to standard threaded interfaces of various brands of actuators, with options for both internal and external threads, as well as an optional swivel joint.

● Noise reduction design and a safe and reliable special composite structure design; 

● High-strength non-standard fabric-reinforced flexible diaphragm with high sensitivity pressure feedback and high control accuracy, equipped with a manual adjustment handlec.

● Pressure interface, allowing the true flow rate to be obtained by measuring the pressure at both ends of the RV (optional); 

● The preset maximum flow rate is achieved through an unrestricted stroke method, with the actuator controlling the flow rate throughout its full stroke; 

● The DPR piston's unique sealing technology ensures sealing requirements while maintaining low friction, using an O-ring seal for safety and reliability.
