Wafer Type Stainless Steel Check Valve, For Water, Wafer End

The Wafer Type Stainless Steel Check Valve for water service is engineered to provide reliable, maintenance-free operation in a wide range of potable and process water systems. Featuring a compact wafer-style design and precision-crafted 316 stainless steel construction, this non-return valve allows flow in one direction while preventing backflow, protecting pumps, pipelines, and equipment from potential damage.

Key Features

• Wafer-Style Compactness
  The slender wafer configuration fits snugly between standard ANSI and DIN flange faces, minimizing face-to-face dimension and saving valuable space in piping layouts. Its lightweight profile reduces installation time and structural load on supporting systems.

• 316 Stainless Steel Body & Disc
  Precision-cast 316 stainless steel offers exceptional resistance to corrosion, pitting, and chlorides—ideal for potable water, seawater, and chemical-laden fluids. Both the valve body and disc are machined to tight tolerances to ensure smooth operation and a bubble-tight seal.

• Elastomeric Seated Disc
  A high-performance EPDM (Ethylene Propylene Diene Monomer) seat is integrally molded around the disc, delivering superb sealing capabilities and low cracking pressure. The resilient seat material is approved for contact with drinking water and exhibits excellent resistance to aging, UV exposure, and a wide pH range.

• Hinge-Pin Assembly
  A stainless steel hinge pin secures the disc in place, providing durable pivot action and preventing disc over-travel. The robust hinge design ensures consistent disc alignment, reduces the risk of chatter or slam during operation, and extends service life.

• Bi-Directional Installation Capability
  Although optimized for uni-directional flow, the symmetric wafer design permits installation in either flow direction, simplifying inventory management and field service. Clear flow-direction arrows are cast into the body for error-free positioning.

• Low Pressure Drop
  The streamlined disc geometry and unobstructed flow path minimize hydraulic losses. Typical pressure drop is less than 0.2 bar at nominal flow, ensuring maximum pump efficiency and reduced energy consumption.

Technical Specifications

Benefits & Advantages

1. Corrosion Resistance: 316 stainless steel construction guards against chemical attack and rust, extending valve life in aggressive water environments.

2. Space-Efficient: The wafer-style form factor reduces piping footprint, making it ideal for installations with tight clearances or retrofit projects.

3. Leak-Tight Performance: EPDM seat and precision machining ensure drip-tight closure, preventing costly water losses and safeguarding downstream equipment.

4. Low Maintenance: With no springs or external power sources, the valve self-operates purely on differential pressure—no lubrication or manual intervention required.

5. Cost Savings: Reduced installation time, minimal maintenance needs, and energy-efficient flow characteristics lower both capital expenditure and life-cycle costs.

Typical Applications

• Municipal & Industrial Water Supply: Prevent backflow in distribution mains, booster stations, and reservoir outlets.

• Pump Protection: Installed downstream of centrifugal or diaphragm pumps to eliminate reverse flow and protect impellers.

• HVAC & Chilled Water Systems: Maintain directional flow in cooling and heating circuits, ensuring system stability.

• Irrigation & Agricultural Systems: Safeguard pumps and pipelines in drip, sprinkler, and center-pivot irrigation networks.

• Process Water & Treatment Plants: Integrated into filtration, softening, and chemical dosing lines to assure unidirectional fluid movement.

Installation & Maintenance Guidelines

1. Orientation: Align the valve so that the flow-direction arrow on the body matches the system’s flow.

2. Gasket Selection: Use compatible rubber or PTFE flange gaskets to ensure a leak-free joint.

3. Torque Values: Tighten flange bolts evenly in a crisscross pattern to the manufacturer’s recommended torque to avoid body distortion.

4. Periodic Inspection: While these valves are designed for trouble-free service, it is advisable to inspect the valve during scheduled system shutdowns to verify seat integrity and confirm free disc movement.

5. Cleaning: For potable water applications, flush the pipeline before commissioning to remove debris that could impair seat sealing.
