304 Stainless Steel Horizontal Swing Check Valve

Keep your plumbing and fluid systems flowing in the right direction with this heavy-duty 304 Stainless Steel Horizontal Swing Check Valve. Designed with a female internal thread connection, this valve prevents backflow automatically — no manual operation required. Available in 2, 3, 4, and 6 point (BSP) sizes, it's a versatile solution for residential, commercial, and light industrial applications.

Key Features

• Premium 304 Stainless Steel Construction: Corrosion-resistant and built for long-lasting durability in demanding environments, including water, mild chemicals, and food-grade systems.
• Swing Check Mechanism: The internal swing disc opens freely under forward flow and seals tight the moment flow reverses, effectively preventing backflow without any manual intervention.
• Horizontal Installation: Engineered for horizontal pipe runs, ensuring reliable sealing performance when installed correctly.
• Internal Female Thread (BSP): Fits standard threaded pipe systems in sizes 2, 3, 4, and 6 point — making it easy to integrate into existing pipework.
• Working Pressure: Rated for pressures up to 850 kPa, suitable for a wide range of residential and light commercial systems.
• Compact & Lightweight: Streamlined design takes up minimal space in tight pipe runs while still delivering robust backflow prevention.

Frequently Asked Questions

Q: What sizes does this stainless steel swing check valve come in?

A: This horizontal swing check valve is available in four sizes: 2 point (approximately 1/4"), 3 point (approximately 3/8"), 4 point (approximately 1/2"), and 6 point (approximately 3/4") BSP internal thread. Please select the size that matches your existing pipework before ordering.

Q: Can this 304 stainless steel check valve be used for drinking water or food-grade applications?

A: Yes. 304 stainless steel is widely used in food, beverage, and potable water systems due to its excellent corrosion resistance and hygienic properties. This valve is suitable for clean water lines and light food-grade fluid systems, making it a versatile choice for both home and commercial use.

Q: How does a horizontal swing check valve work?

A: A swing check valve uses a hinged disc (clapper) mounted inside the valve body. When fluid flows in the correct direction, the disc swings open, allowing flow to pass through freely. When flow stops or reverses, the disc swings back and seals against the seat under gravity and back-pressure, preventing reverse flow without any manual operation.

Q: What is the maximum operating pressure for this check valve?

A: This valve is rated for working pressures below 850 kPa (approximately 123 PSI), making it well-suited for standard residential plumbing, garden irrigation, and light commercial fluid systems.
