Cone Disc Type Control Valves

One area of focus is related to the field of water striking the supply / distribution system and water supply sectors. Can be applied to industrial use and irrigation water supply, as well as several optimal design with the latest technology, striking Com troll valve. We can reduce the impact of vibration and spring protection is designed as a disc-shaped cone.
We supply a variety of valves in combination with an additional device features a Y-shaped torso struck Control Valve. Designed to reduce the pressure loss due to cavitation damage to enemies than the other control valves are especially striking range has a rich flow control valve is adjusted.

Pressure- Reducing Type

Pressure-reducing type will maintain a constant downstream pressure, regardiess of fluctation in the inlet flow or pressure. Pilot and control valve flow stablizer respond to conditions by modulation the main valve with reliable accuracy and stability.

Isolating Type

Isolating type is independent of valvee differential pressure since the line pressure actually servesas the actuator differential pressure. This develops maximum power, ensuring immediate valve response. The upper control-chamber is pressurized to close, and vented to open the valve. the lower control-chamber is usually vented to th atmosphere, but can also be pressurize to power the valve open

 Superior Powder Epoxy Coating

The SJV Control valves is covered inside and cut with epoxy coating. exceptional barrier between the valves base metal and the surroundings. Epoxy coating is suitable forfield overcoating and touch-up without sanding. special surface preparation or the application of heat. the powder epoxy is non-toxis and imparts no taste to water. 

Application
Flow and leakage reduction cavitation damag protection throtting noise reduction burst protection system maintenance savings
