Zero Leakage Ball Valve


The Camseal zero leakage, metal seated forged ball valve from Conval features a cartridge-style, top entry design that saves significant time and money on installation, maintenance, replacement and downtime. With top entry access, maintenance and replacement of the cartridge internals are very convenient, with no effect on existing piping and welds. The Camseal body/bonnet joint is not subject to pipeline stresses. There is no in-line body bolting to loosen or fatigue, so the body remains leak-free. All valves are capable of meeting zero bubbles for four minutes at 50 psi and 1,000 psi nitrogen. Modular internals isolate critical seal surfaces from thermal effects. Conval's exclusive Integral Gland Wrench concentrically loads the stem packing without tools, eliminating stem leaks and extending packing life. Reliable, accurate ball alignment is achieved due to the robust engagement between the one-piece stem and the ball. 

Superior bearing support of the blowout-proof stem ensures proper axial alignment. The custom-engineered flame spray chrome carbide coating has superior bond strength and coating density to provide long-life, leak-free performance even in high temperature and high pressure drop applications. In-line servicing can be accomplished in 30 minutes, restoring zero leakage performance in the event of process application abuse. Camseal ball valves are available in ½" through 4" top entry sizes, with socket weld, butt weld, FNPT and a variety of other ends. Pressure ratings range from ASME Class 900 to 4500. Standard materials include carbon steel SA-105, stainless steel SA-182-F316/F316L, Alloy SA-182-F22 CI.3, SA-182-F91. Standard accessories include ISO-5211 integral mounting pad and electric, pneumatic, or hydraulic actuators. All valves are manufactured under a sophisticated Quality Management System.
