Cast Iron Wafer Non Return Valve: Product Overview

Overview of CI Wafer Type Check Valve

Kelor by Krishna Industries is a leading CI wafer type check valve manufacturer in India, producing high-quality Cast Iron (CI) Wafer Type Check Valves for smooth, one-direction flow control. As a trusted IS standard cast iron wafer check valve distributor India, we ensure these valves effectively stop reverse flow in water, oil, and industrial pipelines. Their slim wafer body saves space and fits easily between flanges.

The valves have a strong cast-iron body and a simple non-return design. Because of this, they are ideal for water treatment plants, irrigation projects, HVAC systems, and general process lines, making us a preferred CI wafer type check valve supplier for EPC projects. As a reliable PN16 CI wafer non return valve bulk wholesale supplier, each valve is rigorously tested for durability and long service life, making it a trusted choice for industries worldwide.

People Also Ask: CI Wafer Type Check Valve FAQ

What is the maximum pressure rating (PN10/PN16) for a CI wafer type check valve?
The standard maximum pressure ratings for our CI wafer check valve are typically PN10 (10 bar) and PN16 (16 bar), depending on the specific body design, size, and operating temperature.
What is the difference between a wafer type and a flanged cast iron check valve?
A wafer type check valve has a slim, lightweight body that is sandwiched between two pipeline flanges using long bolts. In contrast, a flanged check valve has its own integral flanges that bolt directly to the pipeline flanges, making it heavier, longer, and more expensive.
Which IS (Indian Standard) or BS standard applies to CI wafer non-return valves?
CI wafer non-return valves in India are generally manufactured and tested according to IS 13057 or IS 12820 standards, while international equivalents often follow BS EN 12334 or BS EN 593 standards.
Can cast iron wafer check valves be used for high-temperature steam applications?
No, standard cast iron is brittle and not recommended for high-temperature steam applications due to thermal shock risks. For steam lines, cast steel, stainless steel, or alloy steel check valves are preferred.
What are the standard face-to-face dimensions for CI wafer check valves as per IS/BS?
The face-to-face dimensions are exceptionally short compared to flanged valves, usually ranging from 40mm to 100mm depending on the nominal diameter (DN50 to DN600), adhering to manufacturer or specific IS/BS dimensional standards.
How do you properly install a wafer type check valve between two pipeline flanges?
To install properly, align the wafer type check valve between two welding neck or slip-on flanges, ensure the flow direction arrow on the valve body matches the fluid direction, and use appropriate gaskets and flange bolts to tighten it evenly without over-torquing.
What is the typical Cv value and pressure drop across a CI wafer check valve?
The Cv (flow coefficient) value depends on the valve size and disc design (single or dual plate). Wafer check valves generally offer high Cv values with a relatively low pressure drop compared to swing check valves, ensuring minimal flow resistance.
Are CI wafer check valves approved for potable water and drinking water supply systems?
Standard cast iron valves can be used for water, but for potable/drinking water applications, they require an internal food-grade coating (like epoxy or WRAS-approved lining) and stainless steel/bronze wetted parts to prevent rust and contamination.
What is the standard lead time for bulk manufacturing of CI wafer check valves in India?
The standard lead time for bulk manufacturing of CI wafer check valves in India typically ranges from 3 to 6 weeks, depending on the order volume, custom specifications, and current foundry production schedules.
How does the disc design (e.g., dual plate vs. single disc) affect the performance of a CI wafer check valve?
A dual plate (double door) design closes faster and reduces water hammer effect due to lighter plates and spring assistance, whereas a single disc wafer check valve design is simpler and better suited for lower-pressure, slurry, or fluid lines with solid particles.
