Flowline

Relief Valves Spring



Technical data:



Note:
Approximate flow rate for relief valves:
• 2” Spring - 150 GPM Max.
• 3” Spring - 430 GPM Max.

As flow requirements increase, then multiple valves may be preferred, and are permissible. You may find that two of the 2” valves are a better economic combination than one 3” valve. Multiples of either valve are allowed as long as the valves are all set within 10% of each other.

Example:
If a customer requires a flow of 400 GPM, he may choose to use three 2” spring operated valves or one 3” spring operated valve.

Description:



SPM® Emergency Relief Valves provide over-pressure protection for reciprocating pumps, treating lines, pressure vessels and other equipment operating under a variety of pressure and flow conditions. The valves are compact, simple to operate and rely on the system’s pressure to open when a preset pressure is exceeded, and automatically snap shut when the pressure drops.

The valves are externally adjustable, and unlike shear relief valves, which use common nails to trigger the valve, SPM®’s Emergency Relief Valves utilize an internal spring, nitrogen, or rig air to activate opening and closing. Valves are available in 2”, 3” and 4” models.

SPRING
SPM® Spring Actuated Emergency Relief Valves provide over pressure protection for pumps, flow lines, pressure vessels and other equipment operating under a variety of pressures and flow conditions SPM®‘s Spring Actuated Emergency Relief Valves are field-tested products that have long been providing reliable over-pressure protection for well service providers.

The valves are externally adjustable to operate from low pressure/medium flows. Unlike shear relief valves, which use common nails to trigger the valve, SPM®’s Emergency Relief Valves utilize an internal spring to activate opening and closing. Spring actuated relief valves are direct acting, relying on the system’s hydraulic pressure to open when the preset force of the spring is exceeded.
