Wafer Check Valve

Product Overview

The Ball Check Valve is a highly efficient, non-return valve specifically designed for low-pressure systems (≤PN16/Class 150) to prevent reverse flow in water and sludge-containing media. Its robust construction and specialized features make it an ideal choice for applications where reliability, durability, and ease of maintenance are critical.

The valve features a rubber-coated ball that ensures tight sealing even in abrasive or particulate-laden environments, such as wastewater treatment plants and industrial slurry systems. The flanged connection design (compliant with EN 1092-1 or ASME B16.5 standards) allows for easy installation and integration into existing pipelines, reducing downtime and labor costs.

Engineered for low-pressure water systems, this valve is widely used in municipal water supply networks, stormwater drainage, and firefighting systems. Its ability to handle sludge and slurry media (up to 30% solids content) also makes it suitable for industrial applications, including mining, paper mills, and chemical processing plants.

Working Principle

The valve operates through flow-driven actuation:
1.Forward Flow: Fluid pressure lifts the rubber-coated ball, allowing unobstructed flow with minimal pressure drop.
2.Reverse Flow Prevention: When flow stops or reverses, gravity and backpressure force the ball to seat against the valve body, creating an immediate seal.
3.Self-Cleaning Design: The ball’s movement during operation scrubs debris from the sealing surface, ideal for sludge or particulate-laden media.

Key Features

1.Low-Pressure Optimization: Rated for PN10/PN16 (EN 1092-1) or Class 150 (ASME B16.5), perfect for water and wastewater systems.
2.Rubber-Coated Ball:EPDM or NBR coating ensures tight sealing and corrosion resistance in abrasive/sludge environments.
Compliant with WRAS/ACS standards for potable water safety.
3.Flanged Connection:EN 1092-1 (PN16) or ASME B16.5 (Class 150) flanges, pre-drilled for easy pipeline integration.
4.Debris Tolerance:Wide-body design prevents clogging in high-solid-content media (e.g., sewage, industrial slurry).

Operational Advantages

Low Maintenance: No lubrication required; inspection via removable flange cover.

Energy Efficiency: Low head loss (Kv value ≥ 0.8) reduces pump energy consumption.

Sludge Resilience: Rubber coating resists abrasion from sand, grit, and fibrous materials.
