Check valve with BSPP threaded connection, brass housing, NBR seal, stainless steel 302 spring and stainless steel 304 disc to prevent liquids or gases from flowing back. The valve thus offers one-way passage. The disc opens as soon as the minimum opening pressure is reached. As soon as the pressure decreases, the non-return valve closes by means of the spring. The check valve is suitable for air, hot water and cold water systems.

* NPT version available on request.

Info
