Jacketed Ball Valves

Mevada Engineering Works offers Jacketed Ball Valves. These are one-piece split body; side entry design full bore fully jacketed ball valves for maintaining the temperature status of fluid from solidifying. The jackets are designed for 10 kg/cm2 steam/hot water pressure. CS jackets for CS valves and SS jackets for SS valves are provided for enhancing the life of jacket against corrosion. Standard supplies include Œ" NPT jacket connections for inlet, outlet and drainage. Features: special filled TFE renewable seats are provided to withstand the high temperature up to 230°C assuring positive seating; floating ball - where sealing takes place by allowing ball to move under pressure towards the down stream seat to achieve positive tight shut-off; antistatic device - a safety feature, i.e., when static are generated and concentrated on the ball due to solvents and high velocity, the spring-loaded ball are installed on the stem which keeps continuity throughout the valve and discharges the static; pyramidal stem - wherein first stage of defence against leakage, the tapered face of the stem collar gets line contact with body and blocks all leak path after thrust seal (washer) is worn out; blow out proof stem - internally inserted and functions as the back seat for assured stem sealing at all pressures; live loaded gland packing - to avoid frequent and positive gland tightening; long heightened lever - facilitates easy operation and insulation/puffing on the valve body and pipeline; compliance standards - B 16.34, BS 5351, BS 6755-1, ANSI B 16.5, ANSI B 16.10; size - 25-150 mm; class - 150 and 300; and options - long extended stem-stuffing box from 3" to 6" can be provided to suit insulating/puffing and to monitor atmosphere leakage; and pneumatic and electric actuator operations can be provided.
