Frequently Asked Questions

Do hydraulic control valves require electrical power?

Most hydraulic control valves (e.g. F745X level control, 500X pressure reducing) are fully self-operated by pipeline pressure and require no external power. Solenoid-controlled models such as GKZF-1 use AC220V or DC24V.

What is the pressure adjustment range of the 500X valve?

The 500X pressure reducing valve adjusts downstream pressure from 0.1 MPa to 1.6 MPa and works with inlet pressures up to the nominal rating (PN10/PN16/PN25).

What materials are used for potable water applications?

For drinking water networks, models such as the HS41X backflow preventer use ductile iron bodies with EPDM seals and stainless steel internals, compliant with GB/T17219 sanitary requirements.

How is water hammer prevented in hydraulic valves?

Pilot-controlled valves close smoothly and slowly, which avoids sudden pressure surges. Needle valves allow adjustment of the closing speed to match the specific pipeline conditions.
