plunger valves(needle valves), are regulating valves and control and regulate water flow and pressure. The precision is achieved through the fine movement of the shaft, which enables the gearbox to move the piston tube in sliding motion towards opening or closing
1.The plunger valve-needle valve structure design is more reasonable
2.To eliminate the pressure more effectively
3.The plunger valve use more high-quality parts materials
4.The sealing for this plunger valve is more reliable
5.Fluid resistance is smaller
6.The plunger valve(needle valve) is more reliable work efficiency
7.Better eliminate cavitation
8.The plunger valve(needle valve) have more perfect regulation characteristics
plunger valve (needle valves) can be used in applications that require flow or pressure regulation. In water treatment and distribution, dams, reservoirs, power plants and industrial needle valves are used for:
big size gate valve
can be divided in to fan coil type,cage type and special design(customizable)
such as 1.The porous cylinder
2.Conical adjusting type
3.Multi stage cage
TWT plunger valve(needle valve) is good regulating valve
1.Proved by the practice of design
2.Can choose a wide range of sizes and pressure classes of these plunger valve
3.The outlet of the plunger valve can be designed in many forms
4.Mang kinds of materials combinations to be suitable for different conditions
5.Strong structure design and durable
6.The plunger valve(needle valve) suitable for a variety of different uses of the model
7.The valve body and axisymmetric flow streamline
8.Aaaembly operation gear and universal actuator
9.Low head loss
