Expanding Gate Valves

The M&J Valve expanding gate valve model EG valve 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.

DANFLO Surge Relief Valves & Systems

DANFLO surge relief valves (SRV) feature an axial "straight-path" smooth flow pattern and have a large annular flow area for high pressure recovery, low pressure drop and high flow coefficients. Surge control is achieved by "loading" the plug cavity from a regulated nitrogen source.

Danflo-Axial Surge Relief Valves

Pilot-operated valves use line pressure or electronic/pneumatic signals to feed line fluid into selected ports for the desired control action. Special versions of the valve, using an integral power piston, are available for Electro-hydraulic/Servo control.
