All Emerson 2 and 3-inch NPT and 3-inch flanged integral valves can be fitted with an air operated cylinder for remote valve operation. When air pressure is applied to the cylinder, it moves the cylinder rod and the internal valve's operating lever, opening the valve. Upon loss of air pressure, the valve's operating lever immediately returns to the closed position.
Type P326-5: For Type C403-24 and C413-24 double flanged valves.
Type P362-6: For Type C401, C402, C407, C421 and C427 valves (2 and 3-inch sizes).
Type P326-7: For Type C404-24 and C413-24 single flanged valves.
Type P326-8: For Type C204-33 single flanged valves.
The P326 kits feature a spring return design which eliminates the need for an air return. The "rolled" cylinder diaphragm has a special seal that prevents air leakage and minimizes friction. A bellows covers the cylinder rod to prevent build-up of foreign material around the rod, and a filter in the cylinder vent keeps out dust.
