Features * Bolted Bonnet * Replaceable O-ring * Rubber encapsulated wedge, Brass Wedge Nut. * Fusion bonded epoxy coated inside and outside , blue RAL 5017 200 Micron thick * Working pressure from -1 to +16 Bar and working temperature from -10 to +80 ºC
Gate Design
*wedge gate valve Standard gate valves have wedge plates that enter a slot structure to stop the flow. Because of the design, our wedge gates have less motion resistance and require less torque to control the valve.
*parallel slide gate valve Parallel slide valves use a middle disc that slides in the middle of seat rings to create a tight seal.The sliding mechanism can remove particles from the disc to lessen the risk of erosion and leaks.
*knife valve Bladed edge is the main feature of knife gate valve that cuts through a granular solid or thick liquid. The uniquefeature of our gate prevents any small particles from blocking the seat to create a solid seal for certain piping operations.
