One Way Check Valve


Product may vary slightly from image representation.
Check valve, 15mm female compression fittings. This prevents unwanted flow in either direction unless pumped to create sufficient pressure to open the spring loaded valve. The 8 Watt sp20/20 creates sufficient pressure to open the valve. If necessary the internal spring can be cut to reduce the pressure required to open the flow.
