About Southwest Valve & Equipment

Our employees have detailed working knowledge of potable and recycled water systems, water and wastewater treatment plants, pipelines, pump stations, reservoirs, and flow control facilities.  Southwest Valve & Equipment's (SVE) knowledge base provides engineering firms and end users with design support for their projects with the correct products for the application. 


SVE understands the difference between the "correct" product for the application and a product that will "just work" for the application.  A correct product incorporates the longevity of service; takes into account the environment of installation, system continuity, minimizing MRO, and where applicable, modifications to standard product offerings to customize the operation for the required service.

SVE uses published industry text, guidelines, standards, research, and publications combined with our hands-on knowledge and experience of applications and installations.  Our team offers the most up-to-date, sustainable custom manufacturing solutions.  We only source materials from tried and trusted suppliers that meet our exacting standards of quality control.
