THINKTANK bellow seal small-caliber single-base regulating valve is of bellows seal construction on its upper valve cap which completely eliminates the possibility of process media leaking outward from motion clearance of the valve rod, this one of distinguished characteristics of the bellows seal valve.
Purpose:
For the pipeline of water supply and drainage system, which need reduce the pressure.
Suitable temperature: ≤ 90º C
According to the different materials, the temperature is
Up to ≤ 250º C
Suitable medium: Water, air, noncorrosion liquid
Advantages:
Directly act on the lower part of the diaphragm (piston) by the valve-back pressure for reducing the pressure and stabilizing the pressure. It is sensitive and can be used for a long time.
