Pilot Operated Check Valve 12mm & G1/4” Male Elbow Brass 0.5-10bar (7-145psi)

This is a nickel-plated brass pilot-operated check valve. Connection 1 has G 1/4 inch male threads and connection 2 has a 12 mm push-in fitting. It also has a 4 mm push-in actuating connection (check valve). The check valve function can be used for a short intermediate stop of the actuator. If there is control pressure on the 4 mm push-in port, flow can travel in both directions between connection ports 1 & 2. If there is no control pressure on the 4 mm push-in port, flow can only travel from connection 2 to connection 1. It has an NBR seal that makes it suitable for applications within a temperature range from -20 to 80 °C (-4 to 176 °F). The operating pressure range is 0.5 to 10 bar (7 to 145 psi). There is an arrow on the body of the fitting indicating flow direction.

Pros:

• Suitable for neutral and non-corrosive media
• It has manual emergency operation
