VC-210B Series (Brass)

VC-210B Model VC-210B Diaphragm Control Valves are compact, ruggedly constructed and especially designed for the control of water, steam, gas, vacuum, etc.

Valves are single seated, bellows sealed to prevent stem leakage, and may be selected to have the valve action, seating materials and flow characteristics needed for most control applications.

The pneumatic actuator consists of a molded 10 sq. in. EPDM diaphragm enclosed in a die-cast aluminum housing and frame. The readily accessible spring adjusting nut provides easy field adjustment of the starting point within the selected spring range. Synthane gaskets located between the valve bonnet and the actuator frame reduce heat transfer to the diaphragm.
