Product Description

The Orbit Ball Valve utilize the interaction of the sloping surface on the bottom of the stem and spiral groove for the core tilting and rotation. When orbit ball valve begins to opening, the core tilt away from the seat, the line flow passes uniformly around the core face, which reduced the seat wear and erosion from high velocity flow, the core then rotates to the fully open position. In the orbit valve close position, the angled flat surface on the lower stem to mechanically wedge the core tightly against the seat, and generate a needed sealing pressure to ensure the reliable sealing.
CONVISTA’s Orbit Ball Valve is ideally suited for severe application when Big Differential Operation Pressure Happens, Frequently Operation, Pressure and Temperature Differential Request Valve Good Sealing In Long Term or application Not Allowed Downtime Maintenance or Replace Valve Such As: Gas Metering Station, The Outlet And Inlet Of Compressor Station, Suction Of Storage Tank, Emergency Shutdown Application or Hydrogen Service.

Single Seat Design Mandatory Seal, Ensure Valve with Bi-directional Sealing Function
Tilting Core, Mechanical Lifting Stem: No Abrasion When Valve Opening nor Closing, Low Torque Operation
Mechanical Wedge: The angled flat surface on the lower stem provides mechanical wedge tight force to ensure the continuously tight seal.
Dual Stem Guides: Hardened stem slots and tough guide pins control the lift-and-turn action of the stem. So that to control of the ball and meet no abrasion when open or closing function.
Self-cleaning Function: When tilting the core away from the seat. The flow around 360 degree of the core face to clean the foreign material away from the ball and seat.
