Válvula de tapón OVF40

manualde acero inoxidablede dimensiones reducidas

The ADCATrol OVF40 is a series of single seated, two-way overflow valves with inline connections. These valves are mainly used in closed loop systems to ensure that a minimum flow is kept in the event that all connected consumers are in a low load condition or have simply shut down. In these scenarios, the valve will prevent problems such as pressure surges, pump cavitation and overheating. The spring force keeps the valve closed, until the upstream pressure, which acts on the underside of the plug, exceeds the set pressure thus opening the valve and allowing flow to the downstream side. The set pressure is manually adjusted during commissioning by compression of the spring with the adjustment screw located on the top of the valve yoke. The set pressure corresponds to the differential between upstream and downstream pressures across the valve.
