Unique Seat Design..... low torque

Many ordinary Ball Valves have an upstream and downstream seal which permits two-way flow. Sealing depends on the upstream seat being forced against the ball. Just prior to full closure when maximum surge pressure occurs, the upsupported seat can be forced to intrude in to the ball port and the valve can become in-operative.

In the seats of uniflow Ball Valves have pressure relief slots a design feature, prevent this potential failure. When presssure causes the upstream seat to move against the ball and the ball moves downstream the pressure simply leaks into the ball port through the relief slots. The uppstream seat is allowed to return to is original position and the downstream seat provide the leak-proof seal. Therefore, the uniflow Ball Valve can be operated with lower torque at full rated pressure differential across the valve.

The pull away Ball Valve is designed for the begining of the end of Your valve problems, easy and prompt maintenance. Systematic aligning of the central part of the body in comparision to the end connections.

PREMIUM STEM DESIGN

The uniflow has safe blow-out self compensating stem assenbly, which eliminates the possibilities of hazards. With a stem assembly, which eliminates the possibilities of hazards. With a PTFE trust bearing, the stem is inserted through the body cavity and rests against a shoulder machined in the valve body. A PTFE stem seal follower, two bevelled spring discs and adjusting nut. The adjusting nut allows in-line stem seal adjustment; the flexing bevelled spring disc automatically compensates for normal wear as well as seal expansion and contraction from temperature fluctuations. The retaining nut is located beneath the stopper plate permitting the handle to be removed without disturbing the stem adjustment or causing an unsafe condition.
