Description

Features

Working principle

Based on various combinations, refer to the working principles of self-operated flow control valves and self-operated temperature control valves (cooling type/heating type), operating according to the priority action principle.

Main features

1.With pressure balancing function and high sensitivity
2.Low noise, reliable performance, and maintenance free
3.Adopting standard modular design
4.Adjust the flow rate through the standard throttle valve method, which is convenient and fast.
5.Multiple combination controls can be achieved through assembly components

30L01Y/30L01R self-operated flow control valves consists of a control valve with a set flow rate and an actuator.Suitable for flow and temperature control of non corrosive liquids in system pipelines. Working according to the principle of priority action, it is not possible to control two parameters simultaneously.
