The Valtek Valdisk™ is a double offset butterfly valve used whenever high capacity is needed with the lowest possible pressure loss. The Valdisk High Performance Butterfly Control Valves is a Heavy-duty design engineered for high-capacity and low-pressure loss. Ideal for fibrous slurries, liquids, and gas and steam applications under extreme pressures and temperatures.

Features & Benefits:

  • Low profile, low weight body provides a low cost solution
  • Double offset shaft lifts the seat quickly out of the seat to minimize seat wear and allow low torque for great control
  • Metal and soft seat options provide tight shutoff in both flow directions
  • High-performance throttling, even in large pressure drops close to the seat,enabled by high-thrust cylinder actuator coupled with eccentric-cammed disc
  • Greater throttling accuracy assured by low breakout torque provided by jam-levertoggle seating
  • Superior process control with bi-directional, bubble-tight shutoff at high and lowpressure drops
  • Reduced maintenance costs made possible by double-offset disc design, whichminimizes seat and disc wear plus reduces leakage
