Shanghai Sote Valve Co., Ltd., a certified manufacturer serving global markets from North America to Southeast Asia, presents our precision-engineered Water Pressure Regulating Valve. Engineered with selectable WCB, SS304 or SS316 body materials, this industrial-grade valve delivers exceptional pressure control for water distribution systems, fire protection networks, and industrial process lines. Our ISO9001, ISO9004 and OHSAS18001 certified production ensures reliable performance in critical applications worldwide.
The valve's advanced design incorporates three core technological advantages:
- Precision Pressure Regulation – Maintains ±5% set point accuracy under fluctuating flow conditions
- Corrosion Resistance – Optional SS316 construction withstands aggressive media and marine environments
- Zero Maintenance Operation – Self-compensating diaphragm eliminates routine adjustments
Technical specifications include:
| Model Variant | Pressure Range (bar) | Max Temp (°C) | Connection Options |
|---|---|---|---|
| Standard WCB | 1.0-16 | 120 | Flange PN16 |
| SS304/SS316 | 0.5-25 | 200 | NPT/BSP/Flange |
Installation flexibility is enhanced by optional accessories including pressure gauges, strainers, and bypass valves. The corrosion-resistant SS316 variant is particularly suitable for seawater applications and chemical processing, while the economical WCB version provides reliable service in municipal water systems. All models feature tamper-proof adjustment screws and visual position indicators.
With documented installations across six continents and dedicated technical support, Shanghai Sote Valve delivers proven reliability. Our pressure regulators reduce pipe stress by 40% and cut water hammer incidents by 75%, significantly extending pipeline service life. Choose our certified valves for:
- Consistent pressure in high-rise buildings
- Protection of sensitive equipment from pressure surges
- Reduction of water waste in distribution networks
Frequently Asked Questions
Q: What is the typical response time for pressure changes?
A: The valve stabilizes pressure within 2-5 seconds after upstream disturbances, depending on system volume.
Q: Can this valve be used for steam applications?
A: Standard models are for liquid media only. Special steam-rated versions are available upon request.
Q: What maintenance is required?
A: Our diaphragm-sealed design typically requires no routine maintenance. Strainer cleaning is recommended quarterly.
Q: Are test reports available?
A: Factory test certificates documenting hydrostatic and functional tests are provided with each unit.
Q: What is the lead time for custom sizes?
A: Non-standard sizes typically ship within 4-6 weeks from our Shanghai facility.
Q: Can the valve be installed vertically?
A: Horizontal installation is recommended, though vertical mounting is possible with specific orientation requirements.
