The Humphrey SQE-2 is a super quick exhaust valve that rapidly vents air for demanding pneumatic applications. It features three 1/4" NPT ports (inlet, outlet, exhaust) and uses a molded shuttle to deliver fast, high-capacity airflow. This valve can also function as a shuttle or check valve when configured with the exhaust port plug. Compact and durable, it supports improved cycle speeds, reduced backpressure, and quieter system operation. Suited for industrial automation, pneumatic actuators, and motion control systems.
- Responds instantly to pressure changes using a molded shuttle design
- High flow with Cv ??1.42 at 100?psi for fast venting
- Three 1/4" NPT ports (in, out, exhaust) for versatile piping
- Compact body (~1.67" 1.09" 1.36") for space-efficient setups
- No lubrication required; durable zinc aluminum construction
