      ADJUSTMENT SCREWS

      Adjustment Screws are used to control the tension and pressure on spring release mechanics. We have the experience and expertise to offer a high value part consistently by a proven process.

      Material and Specifications

      • Stainless steel
      • 17-4PH
      • Heat Treated H1025 H1150
      • Monel
      • .750″  to 1.5″ Dia
      • 2″-8″ Length

      SPRING BUTTONS

      Spring Buttons are used to control the tension and pressure on springs to keep downward pressure on the disc to seal the pressure realease valve. These are machined with efficiency through a proven process and inspected with lapped sperical ball for accuracy.

      Material and Specifications

      • Stainless steel
      • 17-4PH
      • Carbon Steel
      • Monel
      • .250″  to 6.0″ Dia
      • .100″-2.0″ Length
      • .002 Concentricity
      • 32 Microfinish
      • Sphericrical Radius
      • Concave Radius
      • Hardened as required
      • .002 Straightness

      DISCS AND DISC HOLDERS

      Discs and their respective disc holders seal the valve with under extreme pressure with precision. The dim tol of the mating radius is key to the funcionality of alignment and seating of disc precisely on the nozzle. We pay close attention to accuracy of a seal and the form of “O” Ring  groove.

      Material and Specifications:

      • Stainless steel
      • 17-4PH
      • Heat Treated H1025 H1150
      • Monel
      • .5″  to 10″ Dia
      • .25″-4″ Length
      • .002 Concentricity
      • 32 Microfinish
      • Sphericrical Radius
      • Broached Hex
      • Precise Threaded
      • .002 Radius Profile

      Nozzles

      Nozzles seal against their respective disc and seal the valve with under extreme pressure with precision. The dim tol of the seat surface  is key to the funcionality of alignment and seating of disc precisely on the nozzle. We machine the nozzle with .003R corners and +/-.001 tol.

      Material and Specifications:

      • Stainless steel
      • 17-4PH
      • Inlet radius
      • Monel
      • .5″  to 10″ Dia
      • .25″-4″ Length
      • .002 Concentricity
      • 32 Microfinish
      • Sphericrical Radius
      • Spanner Wrench Holes
      • Precise Threads
      • .002 Radius Profile

      SERVING AS A KEY LINK IN THE PRESSURE VALVE INDUSTRY SUPPLY CHAIN

      Range of Precision Valve Compenents We Machine

      We machine a wide array of components for the valve industry.  We have proven processes and methods to ensure a precise part is machined to spec and shipped protecting critical to quality features. The exotic raw materials are used specifically for the pressure valve field because they can hold up in very harsh, intense environments, for example, the hight pressure of steam or a caustic, corrosive chemical application. These alloys need to be corrosion resistant, yet durable and strong enough to perform under pressure 

      Rehtek’s machine shop works with the following exotic materials;

      • Inconel
      • 4140
      • Hastelloy
      • Stainless steel
      • Invar
      • Hastelloy
      • Monel
      • Nickel
      • 430F
      • 440
      • 321
      • 17-4PH H1150
