Aloyco has been a world leader in the design and manufacture of corrosion resistant valves. Available in sizes 1/2″ to 24″, Aloyco gate, globe and check valves withstand the severe conditions encountered in applications ranging from refining and chemical processing to pulp and paper production.
When your piping system requires pump and compressor protection, specify the Noz-Chek® high peformance, non-slam check valve.
This valve minimizes the damaging effects of water hammer in fluid systems and eliminates valve chatter associated with conventional valves in reciprocating compressor service. The flow area is designed to provide minimal pressure drop across the valve. Noz-Chek valves provide a quick dynamic response, reducing reverse velocity.
Sizes available are 2″ to 84″, in pressure classes 150 up to 4500, API 6A pressure classes 2,000 -15,000, in flanged or butt-weld ends.
Duo-Chek® valves have long been the standard for low-pressure drop flow reversal protection. These valves are made from cast iron, cast steel, stainless steel, and a broad variety of exotic materials.
Duo-Chek offers retainerless designs to API 594 end-to-end dimensions in steel bodied wafer and lug style with a wide variety of trim materials including both metal and resilient seats. Valves come in sizes up to 88″ and pressure ratings up to class 4500.
