Product Features

Non-rising stem structureThe stem height stays unchanged during opening and closing, suitable for limited installation space. Independent stem nut structure avoids jamming and ensures flexible operation.

Zero-leakage elastic seated sealingThe gate plate adopts 304 stainless steel skeleton fully wrapped with EPDM rubber. Bidirectional reliable sealing, tight fit and no water leakage. Firm rubber-metal bonding by professional vulcanization process.

Full straight flow channel, anti-silt designNo dead water cavity inside the valve, low flow resistance, not easy to accumulate impurities. Effectively reduces energy consumption of water pumps.

Multi-protection stem sealingThree-layer O-ring self-sealing structure, top dust-proof device. Internal and external epoxy powder coating, corrosion-resistant and harmless to drinking water quality.

High-quality 304 stainless steelExcellent rust and corrosion resistance, stable performance in tap water, sewage and weak corrosive media.

Technical Specifications

Nominal Diameter: DN40~DN1200Nominal Pressure: PN16 / 1.6MPaHydrostatic Strength Test Pressure: 2.4MPaSealing Test Pressure: 1.76MPaWorking Temperature: 0~80℃Applicable Medium: Tap water, domestic water, sewage, seawaterConnection Standard: National standard flangeDrive Mode: Manual (Electric & Pneumatic customizable)Sealing Material: EPDM

Working Principle

Rotating the handwheel drives the valve stem to lift and lower the gate. The elastic rubber seal closely contacts the valve seat to shut off water flow. Fully opened gate achieves unobstructed water circulation. The non-rising stem is enclosed inside the valve to prevent external corrosion and damage.

Application Fields

Urban municipal tap water pipe network and secondary water supply

Inlet and outlet pipelines of water pumps and pump stations

Sewage treatment plants and urban drainage systems

Building water supply and fire-fighting water pipelines

Municipal water conservancy and environmental engineering

Installation & Maintenance

Confirm model, pressure and specification match pipeline design before installation.

Available for horizontal and vertical installation, handwheel upward. Fasten flange bolts evenly and symmetrically.

Pipe expansion joints are recommended to adapt thermal expansion and contraction.

Regular opening and closing prevents stem rust and blocking, keep valves clean and lubricated.
