ਉਤਪਾਦ ਦੀ ਸੰਖੇਪ ਜਾਣਕਾਰੀ

ਦCast Iron Swing Check Valve is a reliable, automatic non-return valve designed to prevent reverse flow in water, ਗੰਦਾ ਪਾਣੀ, ਅਤੇ ਉਦਯੋਗਿਕ ਪਾਈਪਿੰਗ ਸਿਸਟਮ. Featuring a robust cast iron or ductile iron body with a hinged disc that swings freely on a pin, this valve opens with forward flow and closes automatically when flow stops or reverses — protecting pumps, ਕੰਪ੍ਰੈਸ਼ਰ, and other equipment from damaging backflow. Available with EPDM soft seal (0°C to +80°C) for bubble-tight shut-off or metal-to-metal seal (-10°C to +350°C) for high-temperature applications. The flanged ends conform to BS EN 1092-2:1997 ਮਿਆਰ, ਅੰਤਰਰਾਸ਼ਟਰੀ ਪਾਈਪਿੰਗ ਪ੍ਰਣਾਲੀਆਂ ਨਾਲ ਅਨੁਕੂਲਤਾ ਨੂੰ ਯਕੀਨੀ ਬਣਾਉਣਾ. With sizes from 2″ to 24″ (DN50 to DN600) and pressure ratings PN10/PN16, this valve is suitable for a wide range of applications including drinking water, ਪਾਣੀ ਦੀ ਸਪਲਾਈ & ਡਰੇਨੇਜ, wastewater treatment, ਸਿੰਚਾਈ, ਐਚ.ਵੀ.ਏ.ਸੀ, fire protection, and chemical & energy industries. The fusion-bonded epoxy coating provides superior corrosion protection for long service life. With OEM/ODM customization support, it is the trusted choice for engineers and plant operators worldwide.

Working Principle

The swing check valve operates through a simple yet reliable mechanism:

• 1. Forward Flow (Valve Open): When upstream pressure exceeds downstream pressure, the disc swings open on its hinge pin, allowing flow to pass through with minimal resistance.
• 2. Reverse Flow or Stop (Valve Closed): When flow stops or reverses, gravity and backflow pressure cause the disc to swing back onto the seat, creating a tight seal.
• 3. Horizontal Installation: Swing check valves must be installed horizontally (or in slightly sloping lines) to allow gravity to assist in closing the disc.

ਅਕਸਰ ਪੁੱਛੇ ਜਾਂਦੇ ਸਵਾਲ | ਅਕਸਰ ਪੁੱਛੇ ਜਾਂਦੇ ਸਵਾਲ

Q1: Can a swing check valve be installed vertically?

ਏ: ਨੰ. Swing check valves must be installed horizontally (or in slightly inclined piping) because gravity is required for the disc to return to the seat when flow stops. Vertical installation prevents the disc from closing completely, resulting in backflow.

Q2: What is the difference between soft-seated and metal-seated valves?

ਏ: Soft-seated (EPDM) valves provide zero-leakage (bubble-tight) shut-off and operate within a temperature range of 0°C to +80°C; they are suitable for water, sewage, and mild chemicals. Metal-seated (metal-to-metal) valves operate between -10°C and +350°C and are suitable for steam, high-temperature fluids, and abrasive media, though they have a slightly higher leakage rate (Class IV).

Q3: What is the maximum working pressure for this valve?

ਏ: The standard configuration supports a maximum working pressure of PN10/PN16. Higher pressure ratings are available upon request; please contact our sales team for more information.

Q4: What is the difference between a swing check valve and a lift check valve?

ਏ: Swing check valves use a disc that swings on a hinge; they offer low pressure drop (approx. 0.5 psi), must be installed horizontally, and are suitable for large-bore and low-pressure-drop applications. Lift check valves use a disc that lifts vertically; they offer superior sealing but have a higher pressure drop and can be installed either vertically or horizontally.
