The trunnion ball valve design maintains a reliable seal under high differential pressure without excessive torque, ensuring ...

Refrigeration systems with an air-cooled condenser and receiver located outdoors may need to have additional components installed to prevent the low-pressure switch from opening during startup in ...

Low-pressure controls are a common accessory added to many refrigeration systems. They are normally used to electrically cycle a compressor on and off; however, when and why they do so will vary based ...

The surface area of the plunger and the degree of spring compression determine the amount of pressure necessary to actuate the switch. When pressure on the plunger exceeds that exerted by the spring, ...
