2 Way Pneumatic Operated Cryogenic Ball Valve
Purpose: The Cryogenic valves of JD Controls have been specially designed to solve all the possible challenges of severe working conditions related to cryogens of hydrogen, fluorine, oxygen, ammonia, LNG, nitrogen, methane and acid transferring works. Besides these, the utilization of these valves can be noticed in different industries that include food processing, general sector, treatment and collection of deuterium wastewater to name a few.
These valves have significant role in transferring of gas, freeze drying process, condensation, segregation of air, purification of gas and for performing different types of cooling procedures.
The full range of cryogenic valves has been meticulously designed by veteran professionals who have adopted innovative technology for the fabrication of these valves.
Design: The comprehensive range of cryogenic valves offered by JD Controls includes 2 Way, 3-piece, 2-piece and multiport type valves with 4 way and 3 way design options. All these valves are perfect for low temperature application purpose that involve cryogenic as well as refrigeration methods.
The genuine quality wrought materials fabricated structure of these valves ensures about their reliable operation, compact body, effective air permeability level and optimum strength.
Well chosen metals like titanium, monet, stainless steel and others are used to develop these valves.
The welded structure of their bonnet part guarantees about their leakage proof quality. The Chevron V-ring packing of these valves can be modified by turning of their stem nut part.
The 21/51 model of these valves can be accessed in two different types of angular design options that include 180 degree and 90 degree.
The mechanism of the 90 degree variant of these valves involve diversion of flow from valve bottom part towards one of their outlet at an 90 degree angle which is achieved by turning their handle sans interrupting the flow.
The operation of the 180 degree version of these valves includes flow direction from bottom to any one of the outlet at a 180 degree angular position in such a way so that the flow of 90 degree angular position is completely blocked.
The valves available under 21/51 cryogenic diverter ball valve series possess up to 1500 psi pressure rating and -452 degree F (-269 degree C) temperature level.
The offered valves are equipped with positive ball cavity relief system that inhibits build up of over pressure caused by thermal expansion.
The in built pressure safe stem of these valves is useful for preventing burst and its standard is in sync with the ball of these valves for positive flow direction specifying purpose.
The extended design of valve bonnet is in accordance with industry specified norms and guidelines regarding length and wall thickness level of these valves. The advanced design of these valves is effective in lowering heat transfer rate and in improving their frost resistance properties.
The low thermal stress type design of these valves ensure about their hermetic sealing, outstanding performance level, leakage proof structure and less torque rate.
Standard grade dual graphite seals are used to make the stem seal of these valves flame proof. This sealing design comes in handy for LNG and hydrogen systems. The parameters of these valves can be altered for effective controlling purpose.
These valves are accessible with non extendable stem.
Exceptional flow capacity is attained via quarter turn of these valves.
These valves can be controlled both manually and automatically.
The CPT seat design of these valves is meant for their throttling regulation purpose.
The cutting edge mechanism of these valves has made these perfect for clean room testing and machine installation purpose.
Flame retardant quality.
Burst proof stem.
The unique design of the floating stem seal enables it to withstand various rates of thermal expansion and contraction.
These valves can easily integrate with different ranges of cryo temperature for effective sealing purpose.
Available with actuator mounted design.
Equipped with standard grade padlocking device.
Featured with standard oxygen cleaning system.
