Zero-leakage Ball Valves
The Camseal zero-leakage, metal-seated forged ball valve features a cartridge-style, top-entry design that saves significant time and money on installation, maintenance, replacement and downtime. With tope-entry access, maintenance and replacement of the cartridge internals are convenient, with no effect on existing piping and welds. The body/bonnet joint is not subject to pipelines 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. Valves are available in 1/2" through 4" top-entry sizes, with socket weld, butt weld, FNPT and a variety of other ends. Pressure rating range from ASME Class 900 to 4500.
