Please select your required size at checkout.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does the \"clamp\" or \"quick-release union\" connection mean, and how easy is installation?\u003c\/h4\u003e\n\u003cp\u003eA: A clamp (tri-clamp \/ sanitary union) connection uses a ferrule end and a separate clamp collar to join pipe sections. No threading or welding is required — simply align the valve between two ferrule ends, place the gasket, and tighten the clamp collar by hand or with a wrench. This makes installation, removal, and cleaning extremely fast, which is especially valuable in food, beverage, and pharmaceutical environments that require regular CIP (clean-in-place) procedures.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is 304 stainless steel suitable for food and beverage applications?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. AISI 304 stainless steel is one of the most widely used grades in food processing, dairy, brewing, and pharmaceutical industries due to its excellent corrosion resistance, smooth surface finish, and compliance with sanitary fluid-contact requirements. It resists most mild acids, water, and organic materials encountered in these processes.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum working pressure for this check valve?\u003c\/h4\u003e\n\u003cp\u003eA: This H71W-16P lift check valve is rated for working pressures below 850 kPa (approximately 123 PSI), making it well suited for low-to-medium pressure fluid systems. Ensure your system operating pressure stays within this limit for safe, long-term performance.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does a lift check valve prevent backflow?\u003c\/h4\u003e\n\u003cp\u003eA: A lift check valve contains a disc or piston that rises off its seat when forward flow pressure is sufficient, allowing fluid to pass through. When forward flow stops or pressure drops, the disc drops back onto the seat under gravity or spring assistance, forming a seal that blocks reverse flow — protecting upstream equipment such as pumps and compressors.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What pipe sizes does the DN15–DN50 clamp lift check valve fit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This check valve is available in six sizes — DN15 (½\\\"), DN20 (¾\\\"), DN25 (1\\\"), DN32 (1¼\\\"), DN40 (1½\\\"), and DN50 (2\\\") — covering the most common nominal pipe diameters used in sanitary and industrial systems.
