Electric control valve is an important instrument in industrial automation process control.With the increasing automation level in the industrial field, electric control valve is more and more applied in various industrial production fields.Electric control valve actuator receives actuator signals (0-10v or 4-20ma) to control the valve for regulation, or an intelligent network control system can be formed according to the […]

Double block and bleed valve is abbreviated to DBB valve. It is made up of two ordinary ball valves linked by a common inlet end. The double block and bleed ball valve is a product intended to substitute several connections between conventional valves; as the name suggests, it is a double block and bleed ball

Stram trap valve manufacturer, China steam trap valve factory and supplier for free float steam trap, lever float ball steam trap, inverted bucket steam trap, disc thermodynamic trap, thermostatic steam trap, bimetallic steam trap and other steam traps. What Is A Steam Trap Valve? Stram trap is an automatic valve that automatically drains condensate from

Automatic recirculation valve manufacturer, China pump recirculation control valve factory and supplier. The automatic recirculation valve (ARC valve) is a multifunctional valve whose main purpose is to ensure that the predetermined minimum flow through the centrifugal pump is always ensured. This is important because centrifugal pumps will overheat and cavitation, and will be permanently damaged if idling.The pump

How to calculate control valve diameter size ,let’s give you some brief introduction about how to confirm whether the diameter is suitable for the control valve. Control valve working condition：Medium:Liquid nitrogen，t=33℃，λ=5.9×10^-4kgf/cm3,Pv=15×100kPa,Qmax=15m3/h,the corresponding Qmax p1,p2,△pmin is （530、130、400）×100kPa，Qmin=5m3/h,△pmax = 500×100kPa,s=0.2, choose high pressure control valve ,flow characteristics:linear ,with positioner,what diameter(DN) is suitable for the control valve? 1.Flow capacity：Qmax=15m3/h。 2.Pressure difference：△pmin = 400×100kPa,△Pmax=500×100kPa. 3.Kv value calculation:

Pnematic control valve working condition and how to choose pneumatic control valve After determining the output force of the actuator, select the corresponding actuator for the control valve according to the requirements of the use environment.Pneumatic control valve should be used when there are explosion-proof requirements on site.Considering from the aspect of energy saving, electric

When we choose the electric control valve, we need know Electric Control Valve medium parameters,Electric Control Valve body parameters,Electric Control Valve Actuator parameters, then we can choose the suitable control valve for the clients. The following format is about how to choose electric control valve.Electric control valve technical parameter instruction: 【Form1】Electric Control Valve Medium Parameters No. Name Actual Parameters Examples 1 Medium Name for control

Electric butterfly valves are available in two types: on-off type and intelligent type. The butterfly valve is matched with DSR actuator. It can be operated by inputting control signal (4~20mADC or 1~5VDC) and single-phase power supply. It features powerful functions, compact size, light weight, cost-effectiveness, reliable performance, simple matching and large flow capacity. It is

The control valve structure is divided into the following: single seat control valve, sleeve control valve, cage control valve, double seat control valve,3-way control valve, angle control valve and other common mechanisms. The Specific control valve application is as follows: 1. single seat control valve application: suitable for strict leakage, low pressure difference before and after valve and a certain viscosity occasion. 2.

What is the difference between full lift and low lift safety relief valve?we give you a brief introduction about the full lift and low lift safety relief valve. Full lift safety relief valve: when the static pressure at the entrance of the safety relief valve reaches the setting pressure, the disc will rise to the maximum height and discharge the over-pressure medium in the maximum
