Design incorporates
Spring-loaded, pressure-energized, non-elastomeric lip-seal between the seat and the body. This provides protection against the particle intrusion and prevents body erosion
Minimum number of parts in the gate & seat assembly. One piece seat and gate ensures reliable sealing and ease of field service.
Metal to metal sealing between the gate and the seat.
Special spring-loaded, pressure-energized, non-elastomeric stem packing design.
Stem shoulder that can be back seated against the bonnet to isolate the stuffing box. This allows field replacement of the stem packing while the valve is under pressure.
Non-rising stem, supported by two needle roller thrust bearings, which prevents cavity pressure increase or displacement of cavity lubricant.
Bottom retainer plate, provided as a gate guide during operations.
