Product Description

⚙️ Product Specifications

Valve Type: Wafer check valve Structure: Double disc
Standard: BS5153 Workmanship: Investment casting
Sealing direction: Single-directional Sealing grade: Zero leakage
Temperature: -20°C < T < 120°C Operation: Self-starting

🔍 Characteristics

With a wafer-type structure, it can be directly clamped between two pipeline flanges, eliminating the need for extra installation clearance. Compared with flange-end check valves, it significantly minimizes the overall footprint of the piping system, making it ideal for space-restricted applications.

Characteristics

⭐ Advantages

  • Anti impact, shock absorption and noise reduction: Partial clamp check valves are equipped with buffering mechanisms or damping devices, which can reduce the impact force when the valve disc is closed, weaken the influence of water hammer effect, reduce the noise and vibration during valve opening and closing.
  • Low maintenance cost: The structure has a high degree of modularity, and vulnerable parts such as valve discs and seats can be quickly disassembled and replaced; the inner wall of the flow channel is smooth and not easy to accumulate impurities.
  • Wide material adaptability: The valve body can be made of ductile iron, cast steel, stainless steel and other materials, adapting to various working conditions such as water, sewage, oil, acid and alkali media.
