Every valve is tested with nitrogen @ 68.9 bar (1,000 psig) for leakage at the seat to a maximum allowable leak rate of 0.1 SCCM.

Shell test with nitrogen @ 68.9 bar (1,000 psig) is performed to a requirement of no detectable leakage with a liquid leak detector.

Shell test with water at 1.5 times the working pressure is performed on request with extra cost.

• Pressure and temperature compensation seat design.

• Swing-out design for fast and easy maintenance with the valve in-line.

• Chevron packing design.

• 2-way (on-off) valves with quarter-turn actuation.

Two flats on stem (10) and lever handle (13) indicate open or closed

position of the valve.

Built-in manual locking device (14) allows locking the

valve with a detent either in open or closed position.

Youmay also apply a pad-lock to this device. Pad-lock

hole: 8 mm (0.314 in.)

Compensation seat design requires no

pressure to create a seal.

Under high pressure, seats react on the ball

movement for sealing at upstream and

downstream.
