Cla-Val – Overview
Cla-Val is a Costa Mesa, California-based manufacturer and one of the most recognized names in automatic control valves worldwide. Founded in 1936 and operating out of a global headquarters and factory on Placentia Avenue, Cla-Val has spent nearly 90 years engineering control valve solutions for some of the most demanding fluid control applications on the planet. Their products are found in municipal water systems, fire protection installations, fueling depots, marine vessels, mining operations, and commercial buildings across every major market.
What Cla-Val manufactures is not a commodity valve. Automatic control valves are hydraulically operated, pilot-controlled devices that manage pressure, flow, level, and pump operation automatically without external power sources in most configurations. That self-contained reliability is what makes Cla-Val products a trusted specification in applications where consistent, unattended performance is not optional. From pressure reducing valves that protect downstream piping to altitude valves that manage water tank levels to pump control valves that prevent surge and water hammer, Cla-Val builds the products that keep fluid systems operating within design parameters around the clock.
Cla-Val supports the full specification and installation process with an extensive resource library including data sheets, AutoCAD and REVIT files, product animations, and a dedicated training platform called Cla-Val University. Their Link2Valves configuration tool and Cla-Tools software give engineers and contractors the ability to select, configure, and document valve solutions directly from the Cla-Val platform.

WHY MERION PUMP AND CLA-VAL
Control valves are one of those product categories where the wrong specification creates problems that show up long after the installation is complete. Pressure that creeps above design limits, pumps that surge on startup, water hammer that stresses piping systems over years of daily cycling — these are the consequences of undersized, misapplied, or poorly supported control valve selections. Merion has carried Cla-Val for years because their product eliminates that risk when it is specified and applied correctly, and because the depth of their lineup means we can match the right valve to the right application without compromise.
In commercial plumbing and building services, the Cla-Val products we reach for most often are pressure reducing valves, pump control valves, and pressure relief valves. These are the valves that protect building water systems from pressure fluctuations, prevent surge events when pumps start and stop, and provide the safety relief that keeps systems operating within the parameters they were designed for. In a high-rise building, a hospital, or a large commercial facility, those functions are not optional. They are part of what makes the system work reliably over its full service life.
What backs the product is a manufacturer that has been doing this for nearly 90 years and has the engineering depth to show for it. Cla-Val provides REVIT and AutoCAD files, detailed data sheets, product configuration tools, and a training platform that keeps our team current on the full range of what their lineup can do. When a project has an unusual pressure requirement or a non-standard application, we have the resources and the manufacturer relationship to work through it properly.
FEATURED PRODUCTS
Cla-Val Model 90-01 Pressure Reducing Valve
The foundation of commercial plumbing pressure management. The Model 90-01 automatically reduces a higher inlet pressure to a steady, lower downstream pressure regardless of fluctuating supply conditions or varying flow demand. A standard specification for commercial buildings, high-rises, and any facility where protecting downstream equipment and fixtures from overpressure is a design requirement.
Cla-Val Model 50-01 Pump Control Valve
Designed to prevent the pressure surges and water hammer that occur when pumps start and stop in pressurized piping systems. The Model 50-01 opens and closes at a controlled rate tied to pump operation, protecting piping, fittings, and equipment from the mechanical stress that surge events cause over time. A practical and important specification for any commercial system running booster pumps or multiple pump configurations.
Cla-Val Model 50-20 Pressure Relief Valve
When system pressure exceeds design limits, the Model 50-20 opens to relieve excess pressure and protect the system. Fully automatic and hydraulically operated, it closes tight once normal pressure is restored without requiring manual reset or external power. A reliable safety specification for commercial plumbing systems, booster applications, and any installation where overpressure protection is required by design or code.
