Product Description

Pressure safety valves

  1. Pressure release valve is generally applicable to oil-immersed fully sealed transformers, amorphous converters, American box transformers, on-load voltage regulating switches, high voltage switches, capacitors, etc., installed on the oil tank cover or the side wall of transformers. 2. For screw-connected products, please see the installation size for the hole size on the transformer box cover. 3. Each product is equipped with a safety helmet, but it is only convenient for users to use in the transformer sealing experiment all day, and it must be removed before operation.

APPLICATION

The PRD - 50 pressure safety valve is employed as a safety element in distribution transformers of low rating. In the event
of an explosion-type pressure increase of the transformer tank, the excess pressure must be relieved immediately in order to avoid damage to the tank.

 

CONSTRUCTION

The PRD - 25 pressure safety valve consists of a brass cap, a
conical valve body, a rubber seal between the cap and body
and a coil spring holding the whole system. As soon as relief
pressure is reached, the valve cap lifts off and the excess
pressure is relieved.
The valve then shuts itself down again automatically.
The valve can be infinitely set from 0.2 to 0.7 bar.
The valve can also be equipped with a specially manufactured
protective cap to prevent unauthorized operation of valve.
