The Shear Relief Valve is designed to protect mud pumps in high-pressure drilling environments. When pressure exceeds the rated limit, the piston rises, lifting the shear plate and breaking the shear pin to release fluid, preventing damage to the system quickly. This valve is crucial to the mud pump pressure relief system, ensuring safe and efficient operation within the rated working pressure range.
The SMKST Shear Relief Valve is essential for mud pumps in oil and gas drilling, where it plays a critical role in maintaining the safety and integrity of high-pressure drilling systems. Rapidly releasing excess pressure protects mud pumps and other equipment from potential damage, ensuring continuous and safe operation. Additionally, it is widely used in high-pressure jet drilling rigs and other high-pressure circulation systems for various media, such as oil and water.

Operation and Adjustment
- Pressure Adjustment: The pressure at which the SMKST Shear Relief Valve operates can be adjusted by changing the shear pin position. The shear plate has marked pressure levels for easy reference. Insert the shear pin into the corresponding hole to set the desired operating pressure. Only one shear pin should be inserted at a time.
- Safety Precautions: Only change the bushing size to adjust the relief valve pressure. Do not use wire, welding rods, or other materials, as this can affect the valve’s pressure rating and lead to accidents.
