Frequently Asked Questions – Cast Iron Dual Plate Wafer Check Valve
What is the price of a cast iron dual plate wafer check valve?
Prices vary by size, material, and pressure rating. Standard valves start
from ₹850 per unit. Bulk and project quotations are available on request.
What is a wafer check valve and how does it work?
Wafer check valves fit between two flanges and allow fluid to flow in one
direction only. The dual plate closes automatically when flow reverses,
preventing backflow and water hammer.
Which industries use dual plate wafer check valves?
Widely used in water and wastewater treatment, HVAC systems, chemical processing,
oil & gas pipelines, and industrial process automation.
What are the pressure and temperature limits of these valves?
Standard cast iron dual plate wafer check valves are rated for PN10 / PN16
or ANSI Class 150 and can operate between -20°C to 120°C depending on the
seat material used.
How is maintenance performed on dual plate wafer check valves?
These valves are low-maintenance. The dual plate design is self-closing
and requires minimal inspection. The wafer design allows easy removal for
internal inspection or replacement of seats if needed.
Can this valve be used for corrosive fluids?
Yes, by choosing corrosion-resistant seat materials such as EPDM, NBR,
or PTFE, and using stainless steel discs, the valve can handle many
industrial chemicals safely.
Is this valve suitable for high-flow pipelines?
Yes. The dual plate design ensures minimal pressure drop and high flow
efficiency, making it suitable for medium to high-flow water and
industrial pipelines.
Do you supply these valves for export?
Yes. KELOR supplies cast iron dual plate wafer check valves worldwide
with export-grade packing, documentation, and logistics support.
