How to stop leaking valves

August 7, 2006

For leakproof reliability and precision flow control in liquids or gases, CPV Manufacturing, Inc.''s O-Seal valve system sets the standard. These shutoff, needle, check and stop check valves are rated to 6,000 psi and will function from -20 degrees F to 225 degrees F, depending on seal material selected. O-Seal valves are available in pipe sizes from 1/8" to 2" and tube sizes from 1/4" to 2".

A complete interchangeable valve cartridge with a removable seat separates these valves from most competitive models. This feature enables users to change from any of the four basic O-Seal cartridge designs at will, without compromise to leakproof reliability. At the same time low torque operation is always easy enough for hand control.

Ordered with the popular flat-faced end connections, these valves are slip-in, slip-out, for ease of installation and maintenance. O-Seal valves can be ordered for welded, brazed or separable O-Seal union connections. Finally, O-Seal valves are effective in a wide range of applications because the valve body, stem seal, body O-ring, and other valve components can be specified in a number of different materials.
