Durable Hygienic Non Return Check Valve Butt Weld End One Way Flow Direction

304 / 316L Stainless Steel Sanitary SMS / DIN Hygienic Tri Clamped Non-Return Check Valve Butt Weld End

Product Description:

Hygienic check valve is installed in hygienic pipeline to control medium to flow in one way direction without flowing back. It can protect the medium flow from being absorbed back.

Characteristics:

• ​Adoption of best 304 / 316L stainless steel, anti-aging, acid resistant, long lifetime
• Surface well polished by advanced CNC machine, extereme temperature and corrosion resistant
• Casting steel material, no cutting process
• Compact design, strong flow ability

Dimension Standard Of Weld Connection End:

• ISO 1127: Stainless steel tubes
• ISO 2037: Stainless steel tubes for food industry
• DIN 11850: Stainless steel tubes for the food and chemical industries
• DIN 11866: Pharmaceutical tube, metric
• EN 10357: Stainless steel tubes for food and chemical industry
• 3A
• ASME BPE: ASME Biotechnoloy Process Equipment

Working Principle:

• ​1. The flow pressure of both sides of pipe system equals to each other, the valve is closed
• 2. When flow pressure at bottom side increases, the valve disc is pushes upwards
• 3. Valve is opened and medium flows through the valve accordingly
• 4. When flow pressure of both sides return to balance, the spring force pushes the disc back
• 5. Valve is closed, to stop the medium from flowing back
