Expanding Gate Valves

M & J Featured Gate Valve

The Model EG valve from M&J Valves provides a superior bi-directional mechanical seal because the two-piece gate assembly expands against the seating areas in the open or closed position. The greater the torque, the tighter the seal. The end result is an extremely heat resistant seal that is unaffected by line pressure or vibration
