Ball Valves

Mevada Engineering Works offers Saturn? 2-piece split body design extended neck/stem ball valves applicable for low temperature services in refineries, brine chilling plants, etc., to support insulating/puffing and monitor atmosphere leakage. Features include: long extended stem-stuffing box ? gives sufficient vapour space for freezing prevention; vent hole ? on ball functioned as pressure release device to up stream to prevent dangerous cavity thermal expansion; seats ? special designed PTFE seats, packing and live loaded gland seals assures positive stem sealing and lower operating torque; 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 is generated and concentrated on the ball due to solvents and high velocity, spring-loaded balls are installed on the stem which keeps continuity throughout the valve and discharges the static; blow out proof stem ? top inserted with back up design in stuffing box functions as the back seat for assured stem sealing at all pressures; renewable seat and seals; ISO 5211 mounting pad ? facilitates easy mounting of operating devices (or) hardware; long heighten lever ? facilitates easy operation and insulation/puffing on the valve body and pipeline; compliance standards ? ASME B 16.34, BS 5351, BS 6755-1, ANSI B 16.5, ANSI B 16.10; sizes ? 25-150 mm; class ? 150, 300 and 600; and options ? full or reduce bore, extended stuffing box from 4? to 6?, pad lock arrangement in open/close condition; and pneumatic and electric actuator operations can be provided.
