Vatac Automatic Recirculation Valve is a kind of pump protection device. It automatic protect centrifugal pump when pump body occur cavitations damage or unstable (especially conveying hot water at low load operation medium). Once pump flow is lower than the preseted flow, bypass can completely open to ensure the minimum required flow pump. Even running fully closed, namely running flow is zero, the minimum flow can also pass bypass for Automatic Recycle. Pressure reduced through the multistage bypass pressure reducing valve.

Vatac Pump Protection Valve is suitable for bypass with high pressure differential, maximum pressure differential is 30MPa, and specific choice is determined by factory. Multistage decompression type M type bypass can eliminate noise made by high-speed flow medium; prevent damage of cavitations erosion and braising to valve components.

Vatac Pump Control Valve is equipped with below Main Performance advantages:
» Automatic recirculation control valve including recycling stream decompression facilities, high-pressure medium through the flow around several small diameter, a lot of energy, and reduce stress.
» Pump protection valves have only very low flow recirculation, cooling pump, then pump during normal operation, there is no recycling, saving for a continuous recycling of the consumption of electricity and water.
» Automatic recirculation control valve does not require electrical wiring; do not need two valves in series, one for the adjustment, the other for cutting. And the high-pressure systems are prone to cable and high speed flow to minimize erosion.
» With reasonable design, stable running, no noise, long life, etc., can completely replace the imported products.
» Simple structure, low cost, long life, suitable for low pressure working condition.0
» Easy for installation, can be installed vertically or horizontally on pump outlet.
» Applicable Medium: water, oil, methanol and other liquid medium.
» Working temperature: -196°C~+300°C
