Wafer Type Tilting Disc Check Valve With Heavy Punch

Availability:
Quantity:

A dedicated check valve solution for harsh operating conditions—featuring large diameter, low pressure drop, and high reliability. Through an external swash plate and gravity-assisted structure, it achieves precise and smooth control of medium backflow, making it particularly suitable for low-pressure, high-flow pipeline systems or those requiring slow closing to prevent impact.

  1. Efficient Backflow Prevention to Protect Core Equipment
    Installed at the outlet of pumps and compressors, it prevents equipment reversal damage caused by medium backflow during shutdown.

  2. Intelligent Energy Dissipation to Eliminate Water Hammer Hazards
    Through the adjustable slow-closing function of the counterweight, it decelerates at the final stage of valve closure, gradually cuts off backflow, and effectively absorbs pipeline impact energy to protect pipelines and accessories.

  3. Energy-Saving Preferred Choice for High-Flow Transmission Systems
    Full-port design ensures minimal pressure loss, suitable for energy-sensitive systems such as water supply, power plant circulating water, and petrochemical process pipelines.

  4. Adaptable to Special Media and Operating Conditions
    Highly resistant to particle-containing, high-viscosity, or corrosive media, commonly used in environments like mines, sewage treatment, and offshore platforms.


Key Differences Compared to Regular Check Valves

FeatureWafer-Type Tilting Disc Check Valve (with heavy punch)Regular Swing/Double Disc Check Valve
Closing ForcePrimarily gravity-assisted, adjustable slow-closingRelies on medium backflow impact
Water Hammer ControlActive energy dissipation, highly effectivePassive closing, prone to water hammer
Flow Resistance CoefficientVery low (close to straight pipe)Relatively high
Maintenance ConvenienceExternal components allow inspection without disassemblyRequires valve body disassembly
Condition AdaptabilitySuitable for low pressure, high flow, and media containing impuritiesSuitable for clean media and stable conditions
