Weight Loaded 3" Pressure Relief Valve
[TS-WPRV-3]

Weight Loaded 3\" Pressure Relief Valve
Price includes valve weights for up to 5 PSI. If a different amount of weights are required, please contact us for a proposal.

Design Features

The weight loaded pressure relief valve offers inexpensive relief capacity in a sturdy, trouble free design in 1" though 8" sizes.

Sizes 1" through 4" have standard male threaded connections. Sizes 6" and 8' have standard 125# ANSI flange drillings.

Removable weights have been carefully designed to permit accurate pressure settings in 1/2 PSI increments in the 1 " through 4" size and 1/2 and 1 PSI increments in 6" and 8" size.

The operation of the relief valve is simple. As the service line air pressure reaches the pressure setting, the weight loaded cap is forced upwards off the valve seat. As pressure increases, the cap rises to expose the discharge ports. The flow-through capacity of the valve is such that no damage can be caused to the blower or related systems.

The valve automatically reseats itself as line pressure is reduced.

Since the opening and closing of the valve is essentially the sliding of a piston in a cylinder, the valve is virtually chatter-free. The body and cap of the valve are made of cast iron with close tolerance machined surfaces in the operating areas. The weights are cut from uniform steel plate or uniformly cast to give accurate pressure adjustment.

The weight loaded relief valve was engineered to provide long and dependable protection for your positive displacement blower and associated systems by its simplicity af design. Weight loaded pressure reliefs are designed to protect the blower against damage caused by operation at greater than designed pressure or vacuum. However, they are not intended as pressure regulators.

Maintenance

Application of light oil to the mating surfaces of the cap and body periodically is all the maintenance required on this valve.

Installation

For proper operation, the valve must be mounted in exact upright position.
