Single Seat Control Valve definition and application

Single-seat control valve is only suitable to be applied to clean conditions with critical requirements of leakage and small pressure difference. Single-seat valve is perfect for low differential pressure, while the double-seat valve is suitable for high differential pressure.

Description

Welcome to purchase discount source single seat control valve from our company, which is one of the best China single seat control valve manufacturers and suppliers.

There is a valve body and a valve seat in Single-seat control valve, which is with a small amount of leakage characteristics. The single seat valve unbalance force is huge, which allows comparative low differential pressure than the double-seat valve. When in conditions of high differential pressure and large-diameter, the single seat control valve is better to be accompanied with a positioner. When Nominal diameter 25mm, the single seat valve is a double valve guide structure. By simply changing the connection position of the stem and the valve plug, it can realize the operation of open or close air.

 

Single-seat control valve is only suitable to be applied to clean conditions with critical requirements of leakage and small pressure difference. Single-seat valve is perfect for low differential pressure, while the double-seat valve is suitable for high differential pressure.

 

Single-seat control valve is accompanied by the electric actuator and control valve body. The single seat valve achieve the closed-loop control by accepting 4-20mA or pulse signal, which is output by the regulator, , so that the single seat valve can automatically control the flow, pressure, temperature and liquid level etc. Furthermore, with intelligent electric actuators DCS and PLC, the single seat valve is consisting of more intelligent control systems to achieve digital transmission.

 

Single-seat control valve structure is divided into: single-seat type, telescopic type, double seat type, cage type.

Single-seat control valve is divided into main types: tee type, angle type, high temperature type, low temperature type, bellows type, etc.

 

Single-seat control valve main features and applications:

1) Single-seat control valve is mainly used in the conditions of low leakage and pressure.

2) Single-seat control valve is suitable for confluence mainly used for mixing two fluids into a third fluid; shunt mainly for an fluid into two streams.

3) Single-seat valve is particularly suitable for high viscosity, containing suspended solids and granular fluid media regulation, and it can avoid coking, bonding, plug.

4) Single-seat control valve is suitable for situations with large flow, high temperature and low requirement of leakage.

5) Single-seat control valve is suitable for conditions of temperature ranges: 0 ~ -250 .

6) Single seat Tube-type control valve is used for pole literacy, adjust flammable volatile precious metals and rare media.
