Design Characteristics & Main Applications The MB-series rubber seated knife gate valves we supply have the following design features: (1) The one-piece integral body design minimizes the possibility of shell leakage while maintaining cost effective. (2) The full-port flow passage is formed by compacting two identical rubber seat rings from opposite direction of the body. The full port design minimizes …

Design Characteristics & Advantages The MT-series through conduit knife gate valve has a rectangular disc with a circular opening equal to the full-area flow passageway of the knife gate valve. By lowering or raising the disc, the opening is exposed to the flow or the blind barrier shuts off the flow, respectively. The through-conduit design allows the seating surfaces of …

Design Characteristics The MP-series polyurethane lined knife gate valves we supply have the following distinctive design characteristics: Polyurethane lining: An integral polyurethane liner shall be prepared by cutting it to the correct size and shape for the valve body cavity. It is mounted properly in the valve body cavity to isolate the body from contacting the fluid. The polyurethane liner …

Design Characteristics The MR-series knife gate valves are resilient-seated bidirectional valves. They are one of the most popular family member of knife gate valves, which have several distinctive design characteristics: (1) One-Piece body design: The valve body is cast as a whole, with grooves on the left and right sides as well as the bottom of the valve body cavity. …

Design Characteristics & Functions The MU-Series knife gate valves supplied by Shijiazhuang Metalsin Pipeline Tech Co., Ltd are the most widely used valve variation in various industrial and civil applications. A knife gate valve is a typical parallel gate valve that is designed to handle the flow of fluids containing solids, slurries, or other viscous & fibrous materials. The valve …

Technical Drawing, Design Features & Flange Standards The MSS SP 67 flanged butterfly valve has two integral flanges cast on the body that is either made of ductile iron or cast grey iron. The two integrally cast end flanges can match the standard piping flanges with internal room between the flanges for bolting (Thus, it is also known as “double-flanged” …

Technical Drawing & Design Features The MSS SP 67 lug type butterfly valve, either made of cast iron or ductile iron, has one integral flange with an identical drilling pattern to the piping flanges. Each hole is tapped from opposite direction, meeting in the center of the hole. This arrangement allows the body to be placed between two flanges. A …

Technical Drawing, Function & Advantages The MSS SP 67 cast iron wafer butterfly valve, either furnished with ductile iron or grey iron body, has a flangeless flat body that has a minimum face-to-face dimension, which is equal to twice the required wall thickness plus the width of the packing box. When used in piping connection, the valve will be clamped …

Technical Drawing Design Characteristics & Material Selection Released by American Water Works Association, AWWA C509 is the standard for resilient-seated gate valves for water supply service. The terminology “resilient-seated” is sometimes also expressed as “resilient wedge”. It indicates that the wedge of the gate valve, which has plain one-piece hollow construction, shall be encapsulated/ coated with a layer of rubbers …

Metal seated cast iron gate valves (American standard) may be made of gray iron or ductile iron in accordance with MSS SP 70 and MSS SP 128, respectively. The gray iron shall be in accordance with ASTM A126, while the ductile iron shall be in accordance with ASTM A395 or ASTM A536. They are generally used for various non-shock applications …

Technical Drawings, Design Features & Materials Design features of MSS SP 128 ductile iron gate valves: RF flanged end connection; solid wedge (one-piece); OS&Y rising stem or non-rising stem; bolted bonnet; handwheel operated; metal seated (copper alloy seating surfaces); Class 125 and Class 250 gate valve bodies and bonnets shall be either ASTM A536 or ASTM A395 ductile iron and …

Technical Drawings, Design Characteristics & Materials Cast iron gate valves designed in accordance with MSS SP 70 shall be furnished with ASTM A126 Grade B gray iron bodies and bonnets. Two classes are available: Class 125 and Class 250. We supply Class 125 in both rising stem and non-rising stem styles; Class 250 is only available in rising-stem style. Although …
