At Farris Industrial Valve Corporation, we provide reliable lock-up valves designed to enhance the safety and stability of pneumatic actuator systems. Our lock-up valves are engineered to maintain actuator position during unexpected air supply failures, pressure drops, or control signal interruptions, helping protect critical process equipment and maintain operational integrity.

Designed for pneumatic control applications, our lock-up valves automatically isolate the air supply when abnormal conditions occur, allowing actuators to remain in their last controlled position until normal operating conditions are restored. This makes them an essential accessory for automated valves used in demanding industrial environments.
