Piston Check valves are generally used to protect pumps or similar equipment, allowing the flow in only one direction and preventing flow reversal due to back pressure.

The piston check valves are designed with globe valve bodies, producing an increased drop pressure in the pipeline. This design provides a tight seal as well as a fast reaction to the closure impulse.

Metal seated check valves may not provide drop tight sealing when used in gas system or fluid system with low back flow pressure or fluids contaning particles.

  • Horizontal Fluid Control
  • Vertical Fluid Control with Spring
  • Body to cover joint designed to apply a uniform load to the gasket to assure a leak proof seal.
  • Guided piston to assure a correct seal.
  • Spring to allow a mounting in a vertical line available upon request.
  • Stellite seat provides increased resistance to wear abrasion and erosion of sealing surface.
