Surge Relief Valve & System / Gate and Check Valve
Since 1962 M&J Valve has been a key technology partner to companies across the globe that are involved in the storage, transportation, production or processing of gases and liquids. Attending to the exacting expectations of the oil/gas, petrochemical and chemical sectors, we supply our customers with the top quality, inherently-safe flow control and surge relief solutions they need to raise their productivity and avoid the possibility of causing environmental damage.
Product
M-303 Slab Gate Valves
The M&J Valve Model M-303 is an advanced design slab gate valve for high pressure differential applications in the oil & gas sector. It is designed to simplify installation and upgrades, improve safety and reduce environmental impacts.
4-Way Diverter Valve
The M&J Valve's high quality 4-way diverter valve system is specifically designed for the rigid requirements of bi-directional meter proving.
The M&J 4-Way Diverter Valve is the heart of this system. Its unique design and operating characteristics allows our valve to be cycled hundreds of times per day.
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.
Swing Check Valves
The M & J Swing Check Valve is a one-piece body, top entry design for reliable operation and extended seat seal life. Top entry construction allows field service and in-line maintenance, if necessary.
All major components of the check valve are normally made from cast and wrought forms, allowing the use of a variety of widely accepted materials.
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.
