STORAEN's Multifunctional Pump Control Valve is a high-performance industrial solution engineered to integrate three essential fluid management functions—gate valve isolation, check valve backflow prevention, and water hammer elimination—into a single, streamlined unit. Designed for high-rise building water supply systems and industrial pumping stations, this innovative valve replaces complex multi-valve setups, significantly reducing pipeline footprint while enhancing overall system reliability and safety.
By employing a sophisticated dual-control chamber structure (available in diaphragm or piston types), the valve achieves precise modulation of pump outlet behavior, including slow opening, full opening, slow closing, and complete stopping. This advanced mechanism effectively suppresses destructive pressure surges and protects critical pump infrastructure from water hammer and backflow, ensuring stable operation and extended equipment lifespan in demanding hydraulic environments.
| Nominal Caliber | DN50 – DN1400 | Working Pressure | 1.0MPa to 10.0MPa |
|---|---|---|---|
| Pressure Loss | ≤ 0.01MPa (at 2m/s flow) | Water Hammer Peak | ≤ 1.5x Working Pressure |
| Slow Closing Time | Adjustable 3 – 120 seconds | Action Pressure | ≥ 0.03MPa |
| Media Temperature | 0°C – 80°C | Closure Speed | Fast (80% in 5s) then Gradual |
| Control Chamber | Diaphragm or Piston Type | Sealing Material | Soft Rubber or Metal-to-Metal |
Combines gate, check, and water hammer eliminator functions into one robust body, eliminating multiple failure points.
Advanced slow-closing technology reduces pressure surges to ≤1.5x working pressure compared to 3x in traditional valves.
Full-bore parallel gate design ensures minimal pressure loss, improving energy efficiency by up to 20%.
Spring-loaded disc shuts within 0.2 seconds of flow reversal, protecting pumps from sudden power failures.
Choice between Diaphragm (clean media/low noise) and Piston (high pressure/harsh media) control chambers.
Streamlined body resists debris accumulation and reduces mechanical wear, extending service intervals by 20%.
Reduces installation complexity by replacing three separate valves with one integrated unit.
Stepless modulation via diaphragm chambers for noise-sensitive HVAC and water supply systems.
Compatible with 4-20mA feedback sensors for full integration into PLC and SCADA systems.
Piston-type chambers with hard-chrome plating for wastewater, oil, and abrasive fluids.
Centralized isolation and protection reduces the number of seals and gaskets to monitor.
Fully compliant with ISO 5208 and GB/T 17213 sizing and performance standards.
| Metric | Traditional Multi-Valve Setup | STORAEN Integrated Valve |
|---|---|---|
| Installation Space | High (3 separate units) | Low (1 compact unit) |
| Pressure Loss | Moderate (Cumulative) | Minimal (≤0.01MPa) |
| Water Hammer Peak | Up to 3x Working Pressure | ≤ 1.5x Working Pressure |
| Maintenance Effort | High (3x Seals/Gaskets) | Low (Simplified seals) |
| Pump Lifespan | Standard / Risk of Backflow | Extended / Absolute Protection |
Diaphragm chambers are best for clean media and noise-sensitive areas (like HVAC) providing smoother regulation. Piston chambers are designed for high-pressure, high-temperature, or abrasive fluids (like wastewater) due to their robust mechanical strength.
It uses a two-stage closing mechanism: the main disc closes quickly to stop flow, followed by a gradual closure of the pilot valve (3-120s), which slowly dissipates pressure and prevents destructive shock waves.
Yes, specifically the piston-type model with a hard-chrome-plated surface is engineered to resist scratches from sand, scale, or sludge, ensuring a long cycle life in abrasive environments.
It is ideally suited for high-rise building water supply systems, municipal water distribution, industrial cooling systems, and any pumping station requiring combined isolation and surge protection.
The valves are available in nominal calibers from DN50 to DN1400 and can handle working pressures from 1.0MPa up to 10.0MPa.
Yes, the slow-closing time can be precisely adjusted between 3 and 120 seconds using the external accessories and piping to meet the specific hydraulic needs of your system.
