Two Piece Standard Locking Handle Ball Valve Dimensions DIN3202 ISO 5211 Mounting

Product Description:

1. Seat Strength:

A seat in-tension is stronger than a seat in compression. Because the tensile strength of PTFE in-tension is 3600psi(25MPa) versus only 1800psi (12.5MPa) for PTFE in compression. Greater strength means less fatigue, Superior sealing ability and longer cycle life

2. Lower Torques:

Teyi "in-tension" Seats produce more uniform torque , because the seat deflects into the cavity behind it to accommodate slight differences in machining tolerances or the normal expansion of PTFE as temperature increase. PTFE expands approximately seven times as much as metal.

3. Cavity pressure relief:

Seats are designed to relieve overpressure in the ball/body cavity. This capability is unfluenced by many variables including: fluid characteristics, variations in pressure, seat materials, seat compression, temperssure and thermal cycles.

Positive release of cavity overpressure to the upstream side is assured in bypassing the upstream seat through a drilled hole in the ball. This option is preferred in certain services such as liquid chlorine.

Pressure relief when the valve is in the open position is always through the vent in the top of the ball adjacent to the stem connection.

4. ISO 5211 Mounting Flange for Pneumatic actuator and Electric Actuator.
