Paarth industries has introduced non return valves. These are normally closed, leak proof valves. They are designed to avoid reverse flow in very low or high flow applications, to check in any position. The valves use a normally closed design that is entirely automatic in action, and makes silent operation. It seals in the identical location every time, enabling more reliable sealing and prolonged life. Very nominal pressure is required to open and operate. The valves are manufactured in many different sizes, seats and body materials.
