How a Swing Check Valve Works
Simple, reliable, automatic flow control — no external power needed.
1
Forward Flow — Valve Opens
When fluid flows in the forward direction, the pressure differential lifts the swing disc away from the seat, allowing unobstructed passage through the valve body.
2
Flow Reversal — Valve Closes
When flow stops or reverses, gravity and reverse pressure cause the disc to swing back onto the seat, instantly sealing the flow path to prevent backflow.
3
Tight Sealing
The precision-machined disc and seat surfaces ensure bubble-tight sealing, preventing any reverse leakage that could damage pumps, equipment, or compromise system safety.
4
Wafer Installation
Valve installs between two flanges using stud bolts — no special end preparation needed. Compact design minimizes piping footprint and installation time.

Frequently Asked Questions (FAQ)
Quick answers to common queries about Aluminium Bronze Swing Check Valves.
What is a swing check valve?
A swing check valve is a non-return valve that allows flow in one direction and automatically prevents backflow using a swinging disc. When forward flow pressure lifts the disc, fluid passes through freely. When flow stops or reverses, the disc swings back onto the seat by gravity and reverse pressure, sealing the valve to prevent backward flow. This automatic operation requires no external power or manual intervention, making it one of the most reliable and widely used non-return valve designs in industrial, water, fire, and marine piping systems across India.
What does wafer type mean?
Wafer type means the valve is installed between two flanges without having its own flanged ends. It is clamped between the flanges using stud bolts and nuts. This design significantly reduces the valve’s face-to-face dimension, overall weight, and installation space compared to flanged-end valves. The wafer-type design is particularly advantageous in tight piping layouts, skid-mounted systems, and applications where minimizing weight is important — such as marine installations, offshore platforms, and compact industrial piping arrangements common in Indian plants.
What is the advantage of a single piece body?
A single piece body provides several critical advantages over multi-piece designs: higher structural strength because there are no body joints that could weaken under pressure, fewer potential leak paths since there are no body gaskets, better pressure integrity at elevated temperatures and pressures, reduced maintenance requirements since there are no joint bolts to retighten, and lower overall cost due to simpler manufacturing. In demanding applications like fire fighting, marine, and industrial process piping, the single piece body design provides the reliability and durability that Indian plant operators and contractors require.
Is PN10 suitable for Indian industrial applications?
Yes, PN10 (10 bar / approximately 150 PSI) is one of the most widely used pressure ratings in Indian water distribution, fire protection, HVAC, and utility piping systems. It provides adequate pressure capacity for the majority of non-critical industrial applications. PN10 is the standard pressure class specified in most Indian municipal water supply projects, fire hydrant and sprinkler system installations, HVAC chilled water and condenser water circuits, and general utility piping. For higher pressure applications, PN16 or PN25 variants may also be available on request.
Why is aluminium bronze used?
Aluminium bronze offers excellent corrosion resistance, especially in seawater and aggressive environments, making it the material of choice for marine, offshore, and coastal installations. Compared to cast iron, aluminium bronze does not rust or degrade in wet conditions. Compared to standard stainless steel, it offers superior resistance to cavitation, erosion, and stress corrosion cracking in chlorinated water. Its non-sparking properties make it safe for use in potentially explosive environments. The combination of these properties results in a longer service life with minimal maintenance — making aluminium bronze a cost-effective choice for long-term operations in Indian industrial and marine environments.
Can this valve be used for fire fighting systems?
Yes, this valve is highly suitable for fire protection and sprinkler systems where non-return flow is critical. In fire fighting installations, swing check valves are installed on fire pump discharge lines, fire hydrant risers, and sprinkler system feed mains to prevent reverse flow when the pump stops, maintaining system pressure and preventing water hammer. The aluminium bronze body provides excellent corrosion resistance in stagnant water conditions commonly found in fire protection piping. The wafer-type compact design allows easy installation in tight fire pump room layouts.
Does the valve require manual operation?
No, the swing check valve operates entirely automatically based on flow direction and pressure differential. When forward flow is present, the pressure lifts the swing disc and fluid passes through. When flow stops or reverses, gravity and reverse pressure cause the disc to close automatically. There is no handle, lever, actuator, or external power source required. This automatic, self-acting operation is one of the key advantages of swing check valves — they provide reliable backflow prevention without any human intervention, control system, or power supply.
What maintenance is required?
Minimal maintenance is required due to the robust single piece body construction and corrosion-resistant aluminium bronze material. The swing disc mechanism has a simple design with very few moving parts (disc, hinge pin, and seat). Routine maintenance typically involves periodic visual inspection for external corrosion or damage, verifying that the disc swings freely during planned shutdowns, and checking flange bolting for tightness. In most Indian water and utility applications, the valve operates reliably for years without any maintenance intervention. If maintenance is needed, the wafer-type design allows easy removal by unbolting from between the flanges.
Can it be used in marine applications?
Yes, aluminium bronze is highly recommended and widely used in marine and offshore applications. Aluminium Bronze provides outstanding resistance to seawater corrosion, biofouling, and erosion — making it the standard material choice for marine valves worldwide. Typical marine applications include seawater cooling systems, ballast water lines, bilge systems, fire-fighting systems on ships and offshore platforms, and deck utility piping. The wafer-type compact design is particularly advantageous in marine installations where space and weight are critical. Krishna Industries supplies these valves to shipyards, marine engineering firms, and port authorities across India’s coastal states.
Is this valve available in bulk for projects?
Yes, bulk supply is available for industrial, EPC, government, and fire fighting projects across India. Krishna Industries regularly supplies swing check valves in bulk quantities for water supply projects, fire protection system installations, HVAC projects, marine shipbuilding, and industrial plant construction. Project-based special pricing is available for orders of 50+ pieces with dedicated account management, consolidated dispatch, complete documentation (GST invoice, test reports, MTC), and logistics support to any delivery location in India.
