VP525A, C Pneumatic Radiator Valves

The VP525A,C Pneumatic Radiator Valves are normally open, single-seated valves with straight-through or angle-body construction. The VP525A rating is 180°F (82°C) maximum and the VP525C rating is 240°F (116°C).

NOTE: Solder-body VP525A Valves are obsolete (superseded by VP531 Valves).

Application
These valves typically provide control of two-pipe water or steam systems.

Operation
An increase in branchline pressure from a thermostat causes the valve to close proportionally, modulating the flow through the valve. The valve is fully open when the branchline pressure is at or below the actuator range low end and is fully closed when the branchline pressure is at the high end.
