Control valves ZREDm with an actuator BELIMO

Control valves are suitable for use on cold water, hot water (max. temperature 150°C) and nonflammable gas (max. temperature 80°C). It is highly flexible system which allows one valve to satisfy the needs of industrial requirements.

Description:

• divided characteristic (0...30% Kv_s- equal percentage; 30...100% Kv_s- linear)
• hermetical closing.

>Construction:

Electrical actuator Valves are consisting from two components:
- valve -  valve body (1), valve-seat (2), valve-head (3), valve stem (4)
- actuator: nut (5), electric actuator (6), hand operation (7) supply line (8), position indicator (9).
