As a leading industrial valve manufacturer based in Shanghai, China, Shanghai Sote Valve Co., Ltd. proudly presents the S200x Pressure Relief Valve – engineered to deliver unmatched reliability for commercial infrastructure and municipal water systems. This precision valve safeguards pipelines against dangerous pressure surges while maintaining optimal flow efficiency. With over 15 years of specialized expertise in fluid control solutions, our valves are trusted by engineers across Asia-Pacific for critical water distribution networks.
The S200x series combines robust construction with intelligent pressure management, featuring:
Fail-safe protection against water hammer and pressure spikes
Zero-leakage performance with precision-machined stainless steel trim
Low-maintenance design for reduced operational costs
Broad compatibility with HVAC, fire suppression, and potable water systems
Technical specifications include:
| Parameter | Specification |
|---|---|
| Operating Pressure | 0.2 - 2.5 MPa (adjustable) |
| Temperature Range | 0°C to 80°C |
| Seat Material | EPDM / NBR (optional) |
| Flow Coefficient (Cv) | 25 - 480 depending on size |
Engineers specify the S200x for its three-stage pressure modulation that prevents sudden pressure drops during demand fluctuations. The pilot-operated mechanism ensures rapid response within 0.5 seconds when pressure exceeds preset limits. Unlike conventional valves, our patented diaphragm design eliminates clogging risks from sediment – a critical advantage in municipal applications with variable water quality.
Installation benefits include:
Bi-directional flow capability reducing piping complexity
Flanged connections compliant with EN 1092-2 standards
External pressure adjustment without system shutdown
Test ports for real-time performance monitoring
Shanghai Sote Valve's manufacturing facility utilizes CNC machining centers with ±0.01mm tolerance control, ensuring every S200x valve exceeds industry durability expectations. Our clients report 40% fewer maintenance interventions compared to competitor models after 5 years of continuous operation in high-rise buildings and water treatment plants. With dedicated technical support from our Shanghai headquarters, we provide lifetime consultation on valve selection and system integration.
FAQ:
Q1: Can this valve handle thermal expansion in closed-loop systems?
A: Yes, the S200x is specifically designed to relieve excess pressure from thermal expansion in heating/cooling circuits.
Q2: Is factory calibration available?
A: All valves undergo pre-set calibration at 1.0 MPa unless specified otherwise. Custom pressure settings are available upon request.
Q3: What maintenance intervals are recommended?
A: Annual visual inspection is advised. Internal component service is typically required every 5 years under normal conditions.
Q4: Are special tools needed for installation?
A: Standard flange installation tools suffice. Pilot tube connections require 1/4" NPT threading tools.
Q5: Can it be used for potable water applications?
A: Absolutely. Optional WRAS-certified materials can be supplied for drinking water systems.
Q6: How does it perform with variable flow rates?
A: The proportional control mechanism maintains stable pressure (±5%) across 10-100% flow range.
Q7: What backup options exist during maintenance?
A: We recommend installing parallel valves with isolation gates for critical systems.
Q8: Is seismic certification available?
A: Seismic-resistant models compliant with IBC standards can be customized for earthquake-prone regions.
