OVERVIEW

​The Key-Valve KV-68 is a double-acting pneumatic actuator designed to operate butterfly valves. While specific details about the KV-68 model are limited, it is generally used in conjunction with butterfly valves featuring a GGG40.3 body and a PTFE-lined EPDM seat.

SPECIFICATION

Body Material (GGG40.3): GGG40.3 refers to a grade of ductile iron known for its strength and durability, making it suitable for various industrial applications.​

Seat Material (PTFE-lined EPDM): This combination offers enhanced chemical resistance and flexibility. The PTFE lining provides a non-reactive surface, while the EPDM backing ensures a tight seal and resilience.

FEATURES

Actuator Compatibility:

Double-acting pneumatic actuators like the KV-68 use air pressure to move the valve disc in both directions, allowing for precise control over the valve’s position.
