H100 Low-Temperature Regulating Valve ( Precise regulation of ultracold media)

(1) The valve flow channel is S-shaped, with small pressure drop loss, large flow rate and adjustable range of 50:1;
(2) The design of throttle components adopts CFD analysis and verification, the flow characteristics comply with GB / T 4213-2008 standard, and the flow characteristics have high accuracy,
(3) When the actuator has a locator, the return difference and the basic error are 1.5%, and the control accuracy of the regulating valve is high
(4) Use special combination filler to meet the requirement of microleakage less than 50ppm, and reduce the friction of the valve rod by about 20%
(5) The double sealing structure is adopted to realize the valve seat bidirectional class ANSI V leakage level, and the valve interior parts can be repaired online
