NkeIhe nkedo Iron Swing Check Valve is a reliable, automatic non-return valve designed to prevent reverse flow in water, mmiri mkpofu, na ụlọ ọrụ ọkpọkọ usoro. 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, compressors, and other equipment from damaging backflow. Available with EPDM soft seal (0Celsius C ruo + 80 Celsius) 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 ụkpụrụ, n'ịhụ na ndakọrịta na usoro ọkpọkọ mba ụwa. 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, mmiri na-enye & igbapu mmiri, ọgwụgwọ mmiri mkpofu, ogbugba mmiri n'ubi, HVAC, nchebe ọkụ, and chemical & energy industries. The fusion-bonded epoxy coating provides superior corrosion protection for long service life. Site na nkwado nhazi OEM/ODM, it is the trusted choice for engineers and plant operators worldwide.

Ụkpụrụ ọrụ

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 (ma ọ bụ n'ahịrị na-agbada ntakịrị) to allow gravity to assist in closing the disc.

Q1: Enwere ike itinye valvụ nlele swing kwụ ọtọ?

A: Mba. 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, na-ebute nlọghachi azụ.

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

A: 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, nsị, na obere kemikal. Metal-seated (metal-to-metal) valves operate between -10°C and +350°C and are suitable for steam, high-temperature fluids, na mgbasa ozi abrasive, though they have a slightly higher leakage rate (Klas IV).

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

A: 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: Kedu ihe dị iche n'etiti valvụ nlele swing na valvụ nlele nlele?

A: Swing check valves use a disc that swings on a hinge; they offer low pressure drop (ihe ruru. 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.
