| A shut-off valve is a device used to open/close or isolate flow in water supply and drainage systems, fire protection systems, and industrial piping networks. The product is manufactured in accordance with technical standards, offering high durability, stable operation, and easy maintenance. 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 – Nhiệt độ làm việc: ≤ 80°C – Size: DN50–DN300 (or as required) 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) – Opening and closing are slower than ball valves – Larger size and heavier weight for big DN sizes – Not suitable for very high-temperature environments or special chemical media |
