Cast Iron Wafer Check Valves are non-return valves (NRV) designed to allow unidirectional flow and automatically prevent reverse flow in piping systems. The compact wafer-type design fits easily between standard ANSI, DIN, or BS flanges without requiring its own flanged ends, making it an economical and space-saving solution for water supply, HVAC, fire fighting, irrigation, and general industrial piping systems across India.
KELOR supplies CI wafer check valves from verified and quality-assured vendor partners. These valves are supplied with CI body conforming to IS 210 FG200 grade, precision-machined internals for low pressure drop and quick response, and a range of seat materials to suit different fluid applications. The result is long service life with maintenance-free operation in continuous industrial duty. With sizes from 1½″ to 24″ and three pressure ratings (PN10, PN16, ANSI 125), KELOR covers the full spectrum of CI wafer check valve requirements for Indian projects.
Technical Features
Single Plate vs Dual Plate Wafer Check Valve
CI wafer check valves are available in two disc configurations — single plate and dual plate. Selecting the correct type depends on the application requirements for pressure drop, flow velocity, installation orientation, and cost. Both types share the same wafer body design that fits between flanges, but differ in the disc mechanism and performance characteristics.
| Feature | Single Plate Wafer Check Valve | Dual Plate Wafer Check Valve |
|---|---|---|
| Disc Configuration | One spring-loaded disc hinged at centre | Two spring-loaded discs that open from centre |
| Pressure Drop | Higher — single disc obstructs more flow area | ✅ Lower — dual discs split flow, reduced obstruction |
| Flow Velocity | Suitable for moderate flow velocities | ✅ Suitable for higher flow velocities and pulsating flow |
| Water Hammer | Moderate water hammer on closure | ✅ Reduced water hammer — two lighter discs close faster with less impact |
| Cost | ✅ Lower — simpler construction — standard for water and HVAC | Higher — justified for high-velocity or pulsating flow applications |
| Common Sizes | DN40 to DN300 (1½″ to 12″) | DN50 to DN600 (2″ to 24″) — preferred for larger sizes |
| Best Application | ✅ Water supply, HVAC, fire fighting — standard for most Indian projects | Pump discharge with pulsating flow, high-velocity water mains, large-diameter pipelines |

Understanding Pressure Ratings — PN10 vs PN16 vs ANSI 125
CI wafer check valves are available in three pressure rating systems that are commonly encountered in Indian project specifications. Understanding the differences between these ratings is essential for procurement teams and piping engineers to ensure correct valve selection:
| Rating | Pressure at Ambient | Flange Standard | Common Use |
|---|---|---|---|
| PN10 | 10 bar (145 psi) | DIN EN 1092-1 | Low-pressure utility — irrigation, non-critical water distribution |
| PN16 | 16 bar (232 psi) | DIN EN 1092-1 | ✅ Standard for Indian water supply, HVAC, fire fighting — most common specification |
| ANSI 125 | ~13.8 bar (200 psi) | ASME B16.5 / B16.42 | Projects following American piping standards — equivalent to PN10–PN16 range |

Frequently Asked Questions
1. What is a cast iron wafer check valve?
A cast iron wafer check valve is a compact non-return valve (NRV) designed to allow unidirectional flow and automatically prevent reverse flow in piping systems. The wafer-type design fits between standard ANSI, DIN, or BS flanges without requiring its own flanged ends, making it an economical and space-saving solution for water supply, HVAC, fire fighting, and industrial applications. It is available in single plate and dual plate configurations.
2. What sizes are available for CI wafer check valves?
KELOR supplies CI wafer check valves in sizes from 1½″ (DN40) to 24″ (DN600). The most commonly ordered sizes for Indian projects are 2″ (DN50), 4″ (DN100), 6″ (DN150), and 8″ (DN200). Larger sizes up to 24″ (DN600) are used in main water supply lines, irrigation canals, and fire fighting ring mains where high flow capacity is required.
3. What is the difference between PN10, PN16, and ANSI 125?
PN10 is rated for 10 bar at ambient temperature, PN16 for 16 bar. ANSI 125 (Class 125) is the American equivalent rating system, approximately equivalent to PN10–PN16 range depending on temperature. PN16 is the standard specification for most Indian water supply and HVAC applications. ANSI 125 is commonly specified in projects following American piping standards. Contact KELOR to confirm the correct rating for your project specification.
4. What is the MOQ?
MOQ is 10 pieces. Project orders typically range 20 to 1000+ pieces across sizes. API 598 test certificate, Mill Test Report 3.1 can be provided on request from verified vendors, and GST invoice with E-Way bill provided with every order. WhatsApp size list and quantity for project pricing within 2 hours.
5. Can CI wafer check valves be installed vertically?
Yes — CI wafer check valves can be installed in both horizontal and vertical pipelines. For vertical installation, ensure the flow direction is upward (bottom-to-top) so that the disc closes under gravity and spring force when flow stops. Verify the valve’s orientation marking and installation instructions from the vendor before vertical installation. Vertical installation with downward flow is not recommended as the disc may not close reliably.
6. What seat material should I specify for fire fighting?
For fire fighting systems, specify EPDM seat. EPDM is the standard seat material for fire water service — it provides reliable sealing at ambient temperature, is NBC 2016 compliant for fire water, and offers excellent ageing resistance for long service life. Do not specify NBR seat for fire fighting as NBR has limited temperature capability and may not meet fire code requirements.
7. Can I get OEM branding?
Yes — OEM logo, colour, and packaging can be arranged on bulk orders from verified vendor partners. Custom branding with your company logo on the valve body and packaging is available. Export-standard packing with bubble wrap + carton for domestic orders, or wooden box packing for international export shipments.
8. What documentation is provided?
Every order is supplied with GST invoice and E-Way bill. API 598 test certificates (shell test and seat leakage test) and Mill Test Report (MTC) per EN 10204 Type 3.1 can be provided on request from verified vendors. Hydro test reports, material certificates, and third-party inspection (TPI) reports can be arranged for project-specific requirements.
