Mud pump valve seats are used in on-shore and offshore oil and gas drilling operations and in pumps used in land-based fracking operations. Valves used in these types of pumping equipment operate at a very high frequency – up to one hertz (one cycle per second) – and are prone to high wear and degradation from hysteresis.  Parker’s premium grade valve seats feature our Resilon® Polyurethane which has a high modulus of elasticity to successfully withstand high frequency operation and resist hysteresis.  

Where typical urethane valves may last up to 400 hours, our proven valve seat designs with Resilon Polyurethane have lasted up to 800 hours (400 hours longer) – greatly improving drilling productivity through longer life.  Longer valve seat life means maintenance intervals can be extended and production jobs can be completed before service is required.

Availability
Fluid end valve seats can be supplied as turnkey solutions – complete valve body and valve seats – or as custom snap-on components.

Materials
Our material offering includes our proprietary Resilon® Polyurethane formulations which are chosen for their high performance physical properties which deliver temperature resistance, abrasion resistance, chemical resistance, and resistance to degradation due to material fatigue (hysteresis).  Formulations include:  

• Resilon Polyurethane 4300, high temperature (up to 230°F continuous), high pressure formulation
• Resilon Polyurethane 4301, water resistant formulation
• Resilon Polyurethane 4312, higher durometer (60 Shore D) formulation for improved wear and extrusion resistance
• Resilon Polyurethane 4350, higher temperature capable formulation (up to 250°F continuous) with nanotechnology

Applications
On-shore and offshore mud pumps for oil and gas drilling operations
Fracturing pumps (frack pumps) for land-based fracturing operations
