Designed to replace thru-conduit gate valves in mainline service. Ideal for manifolds, tank farms, pig launchers, river crossings, hot-taps or any other application where a positive, bubble-tight seal is required. The Dual-Seal Ball Valve is capable of acting as an emergency shut-down valve when used with a fail-close actuator.
Repair actuated on/off valves from Asco, Burkert, Granzow, and Parker with these kits that include replacement seals, plunger assemblies, and springs. Automatically or manually start and stop flow in your line with these valve bodies, which attach to your actuator.
YODO VALVES also provides Trunnion mounted ball valves with Doubble piston design, which allows the downstream seat to seal with pressure acting from the upstreeam side of the valve. It aids in better sealing even during leakage through upstream seat.
For easy servicing and extended valve life, Spears® provides numerous maintenance repair kits and replaceable components for all repairable valves. Repair Kits generally include applicable seats, O-ring seals, diaphragms and other components typically subjected to normal operational wear.
Four-way high-pressure block ball valves, designed for use as three-way selectors (T-bore, X-bore, 90° operation) for hydraulic applications for hydraulic applications and Multi-way valve with trunnion-style ball.
Reassemble the seal retainer to the valve body by engaging the mating threads and rotating the seal retainer in the counterclockwise direction. i) Using a torque wrench, measure the torque at the valve stem required to rotate the ball 360°.
Follow up by injecting your regular lubricant / sealant into the upstream fitting. If the regular sealant is not effective, cycle the valve a few times, then inject a heavier sealing compound such as Sealweld® # 5050 Ball Valve Sealant.
