Shift Series

The Shift Series valves are designed for applications that demand leak-free performance.

Engineering Excellence

Wilspec® is one of the three companies in the world that meets the rigorous US and European safety and performance standards.


  • ISO9001
  • UL Recognized
  • ROHS Compliant

The Wilspec® Shift Series of Ball Valves are designed for high pressure air conditioning and refrigeration applications that demand leak-free performance.

The Shift Series valves are forged from brass and precision-machined to guarantee optimum refrigerant flow with close-off torque and minimal pressure drop. The proprietary bi-flow design, utilizing an internal equalization system in the sphere, allows the user to mount the valve in the application without consideration of the flow direction. Each valve features flared copper tubes for efficient brazing of the valves into the refrigerant system. Optional access ports are available with or without an integrated Schrader valve.

Manufactured to the highest quality standard in an ISO 9001 certified facility, these reliable ball valves are available in a variety of connections.
