Cryogenic Ball Valve

PURPOSE               JD Controls has the quality solution for tough applications involving all types of cryogens; oxygen, hydrogen, methane, ammonia, nitrogen, fluorine, LNG, Acid Transfer, Electronics, General Industries and deuterium Wastewater Collection and Treatment, Food Processing.

DESIGN                  The JD Series 2-Piece 3-piece, 2Way, multiport (3 Way,4 way )cryogenic Valves range is designed for cold temperatures, all the way down through the refrigeration to cryogenic range.

The leak-proof integrity of the valve is further enhanced by a welded bonnet design and Chevron V-ring packing, which can be adjusted by a simple turn of the stem nut.

FEATURES -

Positive ball cavity relief to prevent dangerous overpressure due to thermal expansion.

Pressure safe stem assembled inside the body for blowout prevention and matched to the ball for positive flow direction indication.

Effective bonnet extension conforms to industry standards for wall thickness and lengths reducing heat transfer and frost free packing.

High performance/low thermal stress design of valve parts assure tight shutoff,zero body leakage and low torque

Fire safety design with the stem seal design utilizing double graphite seals for fire tight operation. This is especially effective in hydrogen and LNG systems.Modified characteristics for better control

Non-extended-stemavailable ,Quarter turn high flow capacity,Manual and automated performance,Throttling control with CPT seat design,High quality clean room assembly and testing.

Fire safe design,Blow-outproof-stem,Floating stem seal design to tolerate different rates of thermal contraction and expansion  Ability to seal at cryo temperatures
