Cornerstone Valve
Severe Service Ball Valves, Control Valves, Check Valves and Engineered Valve Solutions
Cornerstone Valve designs and manufactures engineered severe-service valves for critical isolation and flow control applications. Its product offering includes top-entry, end-entry and split-body ball valves, rotary control valves and check valves designed for demanding process conditions.
Cornerstone Valve solutions support applications across Oil & Gas production, topside and subsea operations, cryogenic service, petrochemical and refining, power generation, mining, pulp and paper, wastewater and other industrial processes. The company specializes in engineered-to-order valve solutions where pressure, temperature, process media, cycling requirements or operating conditions demand more than a standard valve.
Cornerstone Valve products are available through Westech Industrial for customers seeking reliable valve solutions for severe and critical-service applications. Westech works with customers to review process conditions, application requirements, materials, valve configuration and performance expectations to help identify an appropriate solution. Whether the application involves high-pressure service, cryogenic conditions, abrasive media, demanding isolation duties or a custom-engineered valve requirement, Westech can help customers evaluate the available Cornerstone Valve options.

Need Help Selecting the Right Cornerstone Valve Products?
Choosing the right severe-service valve depends on the application, process media, pressure, temperature, operating conditions, materials, shutoff requirements and installation needs. Whether you are replacing an existing valve, planning a new installation or evaluating an engineered solution for a challenging service, Westech Industrial can help you narrow down the best fit.
Cornerstone Valve offers top-entry, end-entry and split-body ball valves, rotary control valves, check valves and engineered-to-order solutions for demanding industrial applications. Westech can work with your team to review the process requirements and help identify a suitable valve configuration for the application.
Contact our team to discuss your application, request product information or coordinate a product review. Where available, Westech can also help arrange additional technical support to assist your team before moving forward.
Westech Support
Westech Industrial supports customers with product selection, application review, technical coordination and service support for Cornerstone Valve products. Our team can help review process media, pressure, temperature, valve size, materials, shutoff requirements, operating conditions and installation needs to support proper valve selection.
Westech can also assist with replacement requirements, documentation requests, quote support and coordination with Cornerstone when additional technical information is needed. From top-entry, end-entry and split-body ball valves to rotary control valves, check valves and engineered severe-service solutions, Westech helps customers identify practical valve options for demanding industrial applications.
Custom Fabrication and Integrated Solutions
For applications that require more than a standalone valve, Westech Industrial can support Cornerstone Valve products as part of larger integrated solutions. Our custom fabrication capabilities allow us to incorporate valve assemblies into control panels, skids, analyzer shelters, winterized packages and other process systems.
This can be especially valuable when a project requires valves, instrumentation, controls, tubing, enclosures or supporting equipment to work together as a complete package. Westech can help align the Cornerstone valve solution with the broader project design, process conditions, site requirements and installation needs.
By combining Cornerstone severe-service and engineered valve solutions with Westech’s custom fabrication and project support capabilities, customers can reduce coordination challenges and improve consistency across packaged industrial systems.
