ZDHLS electric small-caliber single-seat regulating valve is a deformed product of Cv3000 series ZHLS small-caliber single-seat valve. It is composed of ZHLS valve body parts and electric actuator. It not only has the characteristics of small pressure drop loss, large flow rate, wide adjustable range and high accuracy of flow characteristics, but also has acceptable telecommunication signals for process pipelines. Medium plays an important role in automatic control.

Main technical parameters of adjusting mechanism
Note: 1, symbol 0 and delta indicate specification range.
2. Symbol delta indicates that the flow characteristics of valves conform to the 1EC534-1-1926 standard.
Typical flow characteristic curves
Working temperature curve
Note: 1. 9Cr18 hardening stainless steel is recommended when the temperature of cavitation and flash or water exceeds 100 C.
2. Cavitation, flash, oil prohibition and control valves which are usually in closed state, regardless of the operating temperature and pressure difference, it is recommended to surfacing Stellay alloy.
3, if Cv is less than 0.16, the valve core is all welded with the alloy or 9Cr18 hardened stainless steel.
