Two types of Relief Valves For Mud Pump

Shear type relief valve

Shear type relief valve helps ensure protection for mud pumps, manifolds, and other expensive components used in drilling operations. The relief valve utilizes shear pins to relieve over pressure during drilling and other operations. Hardened stainless steel stems and stainless steel liner subs provide improved corrosion resistance resulting in higher reliability and longer valve life.

Features:

*A metal chart is installed on every valve detailing shear pin selection specifications.

*Hardened stainless steel stems and liner subs provide corrosion resistance.

*There have flange type and thread type.

Reset Relief Valve

The reset relief valve protects mud pumps and mud manifolds while guaranteeing greater safety in operation. The reset relief valve automatically snaps to a full open position when the predetermined pressure is exceeded or can be manually opened by simply pressing the manual release button. The position of the release button indicates at a glance whether the valve is open or closed. They   are designed with a pressure setting indicator (available in metric units) which can be adjusted to any setting within the operating range by simply turning a nut on the top of the valve.

Features:

*Minimum down time for repair;

*Release pressure setting is not affected by vibration during operation.

*Utilizes stainless steel piston and Cadmium-plated sub for improved corrosion resistance.

*Does not require shear pins.

*Fully enclosed bonnet assembly retains grease coating on moving parts extending service life.
