Gate Valves
Pressure seal gate valve
Pressure seal identifies the bonnet-joint sealing arrangement. Body manufacturing method, gate design and stem travel remain separate specifications. Review assembly and seal behavior through startup, normal operation and shutdown.
About the pressure seal gate valve manufacturerThese are family-level options. Confirm the offered series rating and materials against its approved datasheet.
SERIES SELECTION
What should a pressure seal gate valve quotation confirm?
Specify the pressure-seal bonnet joint separately from the gate valve's body construction, stem travel and pressure class. Provide startup, normal, shutdown and thermal-cycling conditions, and request the proposed seal construction, materials, assembly procedure and maintenance access. Agree pressure-boundary and seat tests independently; the bonnet name is not a pressure rating.

- Request the bonnet seal construction, materials and approved assembly procedure.
- Confirm maintenance access and testing; the bonnet name does not establish a pressure class.
- Submit startup, normal and shutdown conditions with line size, maximum differential pressure and cycling frequency. Include quantity, destination, requested date, access restrictions and the required seal/assembly, material and inspection documents. Require the quotation to state the proposed bonnet construction and any open technical points.
