Cat® Well Service Valves and Seats

WELLAchieve lower owning and operating costs, higher productivity, and ultimately, higher profitability. Cat® valves and seats work as a system to sustain extended periods of operation between valve and seat exchanges when compared with other valves and seats.

DESIGNA combination of Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) software was used to develop the valve and seat. Both types of modeling are common in the industry, but our global leadership in high pressure hydraulic sealing design and laboratory validation has modernized the flow and contact characteristics of valves and seats.

Cat industry standard 4 and 5 series valves and seats are designed with the same inner diameter as 5 series seats, so Cat 4 series valves flow more water than any other standard lift 5 series valve on the market, making Cat valves equally efficient with nearly all common plunger sizes.

MODE OF FAILURE CATERPILLAR DESIGN MITIGATION

Abrasion > • Improved urethane material and geometry• Proprietary heat treating and case hardening process

Impact Damage >• Increased metal-to-metal contact area• Optimized valve body geometry and mass; seat geometry• Material heat treatments and case hardenings• Designed urethane geometry for flexibility

Urethane Detachment > • Proprietary urethane bonding process• Over-molded exterior profile moves with valve seat, not against

Wash Out > • New geometry optimizes fluid flow exiting the valve based on two-phase flow analysis
