Flanged swing check valves ensure unidirectional flow and prevent backflow in LPG and NH3 systems. They are essential for protecting equipment and maintaining system efficiency.
Designed to promote maximum pump efficiency, these indicators enable bobtail operators to visually inspect liquid flow conditions. With glass on both sides of the indicator, flow can be observed from either side, even under some poor light conditions. The integral swing check also serves as a back-check valve to prevent reverse flow and product loss if the hose fails in a loading operation. By installing an indicator on the upstream side of the pump, suction conditions can be observed, and the pump speed adjusted to obtain the maximum possible flow rate without cavitation.
