BYPASS VALVE

A valve mechanism that assures system fluid flow when a preselected differential pressure across is exceeded; the valve allows all or part of the flow to bypass the filter element.

SADDLE VALVE

Valve body shaped so it may be silver brazed or clamped onto a refrigerant tubing surface.(TAP-A-LINE)

SERVICE VALVE

Manually operated valve mounted on refrigerating systems used for service operation.

POSITIVE CRANKCASE VENTILATION (PCV)

System for removing blow-by gases from the crankcase and returning them through the intake manifold to the combustion chamber where the recirculated hydrocarbons are burned. A PCV valve controls the flow of gases from the crankcase to reduce hydrocarbon emissions.

SOLENOID VALVE

Electromagnet with a moving core. It serves as a valve or operates a valve.

OBLITERATION

A synergistic phenomenon of both particle silting and polar adhesion. When water and silt particles co-exist in a fluid containing long-chain molecules, the tendency for valves to undergo obliteration increases.

BLEEDER VALVE

A valve designed to slowly relief a liquid or gas form system.

BYPASS

A pipe or duct, usually controlled by valve or damper, for conveying a fluid around an element of a system.

CLEARANCE SPACE

Space between top of piston and the valve plate.

DIFFERENTIAL PRESSURE RELIEF VALVE

A valve whose primary function is to limit differential pressure.
