Camtech Pressure Balanced Lubricated Plug valves robust in construction and easy In-Line maintainability. These valves are used where existing pulsating or static high pressures are present. These valves are suitable for medium that are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, electric power industry etc. under nominal pressure of Class 150-2500 Lbs and working temperature of –29~180°C.
Uniqueness of dynamically and pressure balanced design together with inverted plug design, assure prevention of locking, which has been the problems of conventional design at higher pressure application. Pressure Balance Lubricated Plug valves are manufactured using a wide range of materials to suit the service applications.
The benefit of dynamic pressure balance plug valve offers is that it ensures equalized pressure between the plug and upper and lower body chamber. Pressure is balance by the two holes in the plug which connects the plug port to upper and lower chamber. The hole in the upper end is provided with a check valve so that the pressure is always equal to the larger chamber and always equal to or greater than the line pressure in the small chamber. Few silent features are indicated as below,
Valves are with Double Block and bleed feature.
Easy inline maintenance.
In the event of the plug lock-up, it is possible to inject lubricant to the valve in service.
Leak tightness of the operating system.
Assured stem tightness by means of gasket and packing between the stem and the body.
Double injector for lubrication can be provided on request.
Hardfaced seating faces resist erosion.
Low emission packing set available for special service.
Drain and Vent are provided as standard features.
