| Gate valve is a device used to open/closer or isolate the flow in water supply and drainage pipeline systems, fire protection systems, and industrial systems. The product is manufactured according to technical standards, offering high durability, stable operation, and easy maintenance. Common types of shut-off valves: – Gate valve: Used to open/close the main flow, equipped with a supervisory switch to monitor the open/close status and transmit signals to the central control panel. – Gear - operated butterfly valve: Compact design, quick opening and closing by handwheel, saving installation space. – One-way valve: Allows water to flow in one direction only, preventing backflow that may damage the pump. Technical specifications: – Brand: Penguin – Origin: Malaysia – Body material: High-quality PP plastic / ductile iron / grey cast iron – Shaft material: Stainless steel – Valve disc: EPDM rubber-coated cast iron (model dependent) – Connection: Flanged / threaded – Standards: ISO 17885, ISO 3458, ISO 3459, ISO 3501, ISO 3503, ISO 7; pressure rating PN16 – Applicable for PE pipes SDR9–SDR17, black. – Working pressure: PN10 / PN16 – Working temperature: ≤ 80°C – Size: DN50–DN300 (or as required) Key Features: – Characteristic grooved-end design: Both ends of the valve are factory-grooved, allowing direct connection to pipes through couplings without flanges or welding, reducing the overall weight of the system. – Độ bền cơ học cao: Thân gang cầu giúp van chịu được va đập và áp suất đột ngột tốt hơn gang xám. – Thick epoxy coating: Protects the valve from oxidation caused by environmental conditions, especially suitable for Vietnam's hot and humid climate. Benefits: – High sealing performance, minimizing leakage during operation – Smooth operation with soft open/close, requiring minimal operating force – Good pressure resistance, suitable for PN10–PN16 – Durable materials with corrosion resistance for long service life – Easy installation and maintenance, with convenient replacement of components – Widely used in water supply, fire protection, and industrial applications Disadvantages: – Not suitable for flow throttling (recommended for full open/close only) – Slower opening/ closing time comprared to ball valves – Larger size and heavier weight for big DN sizes – Not suitable for very high-temperature environments or special chemical media Applications – Fire protection system: Installed at pump stations, apartment risers, and sprinkler branch lines. – Water supply system: Used in high-rise buildings and industrial zones. – HVAC system: Controls water flow in cooling towers and chillers. |
