OCV 125-27

Diaphragm-Actuated, Double-Chambered, Rigid Sealing, Pump Control Globe Valve With Lift-Check Feature

OCV 125-27, is a diaphragm-actuated, double-chambered, rigid sealing, pump control globe valve with lift-check feature, activated by the pressure of the pipeline. The valve minimizes pump starting and stopping surges by slowly opening at pump startup and slowly closing prior to pump shutdown. Valve internal assembly (Lift Check) closes the valve before pressure reversal. Dual chamber assures full opening at any flow, thus minimizing pressure losses.

Features & Benefits

Designed for mining — built to perform in the harshest conditions
  • Engineered to minimize cavitation and extend service life
  • Delivers consistent performance with high stability
  • Optimized for high pressure and non-clean fluids applications
Single valve series covering a wide pressure range — up to 740 psi with a single body
  • Same body for low and high pressure applications
  • No need to switch valve series — simplifies selection and maintenance
  • Reduces spare parts inventory — lowers cost and streamlines logistics
Double-Chambered actuator
  • Allows valve to fully open at any flow
  • Minimizes the head loss across the valve
Internal Lift Check mechanism
  • Closes the valve instantaneously, before pressure reversal
  • Reduces surge events during pump failure events
The control-trim is fitted with a HIGH-CAPACITY control filter suitable for industrial applications
  • Increases valve reliability and reduces periodic inspection/maintenance labor
For non-clean solutions, a full port motorized ball valve is used (instead of a solenoid valve)
  • Results in higher reliability
Stainless Steel position indicator rod
  • Enables smooth, precise tracking of valve opening
Position limit switch
  • Enables remote confirmation of valve opening or closing failure
