Valve Plates

With our specialty in high precision machining, Tolerance Masters is a major source for custom valve plates. As an integral component of hydraulic pump applications, valve plate designs have to meet stringent specifications. 

For durability, high pressure fluid capacities, and strength, we manufacture custom valve plates from materials compatible with the service conditions of your particular application. Supported by a technically trained workforce, our modern facility houses CNC controlled machining and grinding equipment that allows us to manufacture high-precision valve plates with tolerances measured in below one micron. Our machinists have in-depth knowledge of metals and machining technologies. Their proficiency allows them to leverage the advanced capabilities of our equipment to machine and grind workpieces characterized by their consistent quality, dimensional accuracy, and flatness.

We have the capacity to manufacture valve plates measuring up to 10” in diameter, thicknesses vary based on application. Materials of construction include all grades of aluminum, stainless steel, specialty alloys, and pure carbide. Our capabilities allow us to manufacture highly complex, specially designed valve plates for demanding applications in the aerospace, defense, transportation, medical, and satellite systems industry.

As a supplier to leading OEMs, our manufacturing processes are backed up by an ISO 9001:2008 and AS9100D quality management system. We pay detailed attention to quality from the moment we receive the raw materials to the final packaging and shipment of your finished products.
