Valves & Fittings
Knight Pumps Australia hase an extensive range of check valves, foot valves and fittings including NITO stainless steel couplings.
NITO Stainless Steel Couplings
STAINLESS COUPLINGS
STAINLESS STEEL COUPLINGS ARE SUITABLE FOR FOOD CONTACT, USED IN THE CHEMICAL-TECHNICAL INDUSTRY AS WELL AS THE PHARMACEUTICAL AND FOOD INDUSTRY
NITO Stainless steel couplings are available in 1/2", 3/4" and 1" dimensions. Acid-proof stainless steel – AISI-316 protects against corrosion and thus resists most organic acids in all possible concentrations as well as the majority of saline solutions – even at high temperatures (max 25 bar)
Check Valves - 426 Series
Check valves for chemical transfer applications
The 426 Series Check Valve design promotes multiple configurations to fit the exact end use application. Gray PVC with 1 psi stainless spring and ball is the standard configuration. Most PVC and White Filled Polypropylene configurations are available as NSF Standard 42 Certified. Nylon, PVDF (Kynar®) and Glass Filled Polypropylene are available for chemical resistance applications. MakroBlend is an NSF Standard 51 Certified Material. Hastelloy is a superior chemically resistant spring material. Teflon® balls are standard with Hastelloy springs for chemical resistance applications.
Check Valves - 685 Series
The 685 Series Poppet Check Valve incorporates a thin elastomer disc supported by a poppet that seals on the seat. Pressure in the flow direction moves the seal off the seat first before pressure builds enough to move the poppet away from the seat. The 685 Series Check Valve maximum operating pressure of 125 psi covers a wide range of air and fluid applications. The 685 Check is a compact design with a light cracking pressure, high flow rate, and a positive seal at very low back pressure or slight vacuum. For higher cracking pressure applications, an embedded o-ring poppet is substituted for the standard elastomer disc poppet.
Foot Valves - 426 Series
Non return Foot Valves
The 426 Series Foot Valve design promotes multiple outlet end configurations to fit the exact end use application. The inlet end is a 3/8” Hose Barb with a 40 Mesh Stainless Suction Strainer screen installed. Gray PVC with 1 psi stainless spring and ball is the standard configuration. Nylon, PVDF (Kynar®) and Glass Filled Polypropylene are available for chemical resistant applications. MakroBlend is an NSF Standard 51 Approved Material. Hastelloy is a superior chemically resistant spring material. Teflon® balls are standard with Hastelloy springs for chemical resistant applications.
