■ overview

HTSThe insulation jacket single seat regulating valve isCV3000One of the series products.

HTSThe insulation jacket single seat regulating valve core adopts an upward guiding structure, with a compact valve structure and aSThe streamlined channel reduces pressure drop loss, increases flow rate, has a wide adjustable range, and high accuracy in flow characteristics, which is in line withIEC534-2-1976Standard. Suitable for occasions that require insulation. When the crystallization temperature of the process medium is lower than the ambient temperature or the fluid temperature decreases, causing an increase in viscosity or solidification of the fluid, a steam insulation jacket device is added at the valve body and upper valve cover to meet the process control requirements of the process medium.

The leakage of the regulating valve meets the requirementsANSI B16.104Standard. The regulating valve is equipped with a multi spring diaphragm or cylinder actuator, which has a compact structure and high output force. This product complies withGB/T4213-92Standard.
