Range of Materials
Standard body/bonnet materials include ten grades of carbon, low alloy and stainless steels. For special applications they can be supplied in other grades of alloy and stainless steel. There’s a full range of trim materials to match any service. Optional packing and gasket materials are available for a full range of service conditions.
All valves are available with hand-wheels, gearing, electric motor actuators or pneumatic or hydraulic cylinder actuators.
Easy MaintenanceBy providing a choice of wedge types, the valve can be matched up with the service conditions, thus enhancing operability and lessening the possibility of binding. Full body wedge guides assure wedge-to-seat alignment.
Threaded or welded seat rings are easily accessible for repair or replacement. Packing swing bolts on most valves simplify packing replacement. All CNI bolted bonnet designs facilitate fast disassembly.
Rugged construction provides years of reliable service. T-head stem/wedge design permits the wedge to self-align for extended seat life. A two piece packing gland prevents cocking and stem damage.
