The AOP NS2 Series is a slab-gate, non rising stem, full bore, through conduit gate valve designed to work in variety of tough environments. NS2 valves are in full compliance with API 6A & ISO 10423, and are available in flanged end connections from 2-1/16” bore to 7-1/16” bore, and in threaded end connections from 2-1/16” to 4-1/16”, pressure ratings 2000, 3000 and 5000 psi.
Features:
- The slab gate assures a bi-directional seal and removes the possibility of pressure being trapped in double block conditions. The slab gate releases the body pressure if line pressure decreases.
- The seats are floating type for easy replacement. The seat has an insert for positive sealing. Metal to metal seating is available upon request.
- Metal-to-metal sealing between body and bonnet interface are stable and environmentally resistant.
- The stem packing is re-energizable with the valve in line and under pressure using the injectable packing fitting. The valve is also equipped with two body fittings for easy draining and lubrication.
The NS2 Series gate valve is bi-directional and can be installed in line in either direction. NS2 valves have the advantage of being easily adapted for use with a variety of actuators; reverse acting, direct acting, pneumatic and hydraulic.
