A non-return valve allows a medium to flow in only one direction and is fitted to ensure that the medium flows through a pipe in the right direction, where pressure conditions may otherwise cause reversed flow. The flow through the non-return valve causes a relatively large pressure drop, which has to be taken into account when designing the

IGEM/G/10 - Non-return valves. This document is largely based upon the original requirement for NRVs as agreed between British Gas and Energy Utilities Alliance, as published in IM14 in 1989. The requirements of this document were incorporated into IGE/GM/8 Part 1 when it was published in 2005, however as the need for NRVs is not limited to

A non-return valve lets the fluid flow in one direction. As the name implies, the primary function of a non-return valve is to keep the flow of fluid in just one direction. When fluid in the line reverses direction and begins to flow back the way it came, a check valve serves to stop or prevent the backflow by allowing flow in one direction.

Non-Return Valves RSV. Non-return valve for maintaining the vacuum in the case of a power failure or a failure of the vacuum generator. Can also be used with energy saving systems when handling non-porous materials. May be installed in any orientation. Product Details.
