Product Description

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

Product Features

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
Product Parameters
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:

flow control
Pressure regulation
freed
Reservoir entrance

big size gate valve

Size:DN100-2200
Pressure:PN0.6-6.4Mpa
