Series 2000~5000psi Gate Valve Expanding Gate Design Neway's expanding-style gate is a two-piece gate design, connecting with the stem through the gate major segment, the contact surface between the major segment and the minor segment is milled V design. Neway API 6A series GE gate valve is a soft seal or metal-tometal seal between gate and seats, expanding-style gate design. Size range is from 2-1/16 to 4-1/16 pressure ratings from 2.000 PSI to 10.000 PSI, temperature range is from -46 to 121 , material classes range from AA to FF, and available end connection is double flanged and threaded end. The V design can force the two segments out and into contact with the seats when the gate moves up and down, and can produce a positive acting force against both the upstream and downstream seats or gate guiding plates simultaneously when the gate is at full close or full open position. Obviously the expanding-style gate does rely on operation force from handwheel instead of the line pressure to seal, so it's recommended for applications when a tight mechanical seal is required. Expanding-style Gate Availability Nominal Size Working Pressure (PSI) 2000 3000 5000 10000 Upper/lower roller thrust bearing to minimize operation torque. 1-13/16 - - - RS-L 2-1/16 NRS NRS NRS RS-L 2-9/16 NRS NRS NRS RS-L Expanding Gate Design 3-1/16 3-1/8 4-1/16 - - - NRS NRS NRS NRS NRS NRS RS-L - RS-L Expanding-style gate structure to extend the seal surface life of gate and seats. Non-rising stem design to permit valve installation in closer quarters. Note: 1) NRS means non-rising stem gate valve; 2) RS-L means rising stem gate valve with lower balancing stem. Slab Gate Design Neway slab-style gate is a simple one-piece & solid gate design, featuring metalto-metal seal between gate and seats, so as to apply for the most severe and demanding service condition, including corrosive and abrasive fluid environments. A floating-style seat is designed to match with the slab-style gate. In which, a belleville spring and O-ring between each seat and body ensure a tight seal against the slab gate. The slab-style gate design creates a positive seal by moving the floating seat against the gate with the use of spring energized force, whether low line pressure or high line pressure.

Series 2000~5000psi Gate Valve Series 10000~15000psi Gate Valve D Neway API 6A series GB gate valve is a simple slab gate, double stems, and metal-to-metal sealing design providing safe & dependable service in 10000~15000psi working pressure application. The import difference from expanding gate valve is to design a lower balancing stem at the bottom of gate, so as to reduce the operation torque. Available size range is from 1-13/16 to 4-1/16 , temperature range is from -46 to 121 , material class range from AA to FF.
