Product Introduction
What is a bolted bonnet in a gate valve?
The Bolted Bonnet Gate Valve is a gate valve that provides sealing in larger valves and high pressure applications. The bolted bonnet fitting for gate valves is the most popular fitting and it is used for most gate valves in industrial use today. Unlike threaded and union bonnet valves, in a bolted bonnet gate valve, where the body and bonnet are bolted together and flanged together, a bolted bonnet connection requires a gasket to seal between the body and bonnet. connection between.
Bolt-on bonnet gate valves are designed to provide maximum service life and reliability while offering a wide range of materials, actuators, and ease of maintenance and operation.
What are the different types of bonnets for bolted bonnet gate valves?
Some different types of hoods include:
Screw-in bonnets: They are mostly available in small sizes and ensure that the seal does not leak.
Union Bonnets: They are held in place using retaining nuts located on the lower edge of the bonnet. these nuts screw it in
Pressure Seal Bonnets: They are suitable for high pressure applications because they use internal pressure to form a good seal. The pressure-tight valve cap has a downward facing cup that fits into the valve body and is forced outward as pressure builds.
Bolt-on Bonnets: They ensure adequate tightness in high pressure applications.
Application of Bolted Bonnet Gate Valves
These high quality bolt-on bonnet gate valves are commonly installed in a variety of services in the oil and gas industry, chemical and petrochemical industries, onshore and offshore drilling/refining, and the power industry. Bolt-on bonnet gate valves have been successfully installed in applications worldwide where tight shut-off is required.
Gate valve bolt-on bonnet fittings are the most popular fittings used on most gate valves in industrial use today.
Unlike threaded bonnet valves and union bonnet valves, bolted bonnet connections require gaskets to seal the joint between the body and bonnet. On low pressure valves, use sheet gasket material and metal gaskets to seal bonnet gate valves at higher pressures.
Material range
Standard body/bonnet materials include nine grades of carbon steel, low alloy steel and stainless steel. For special applications, they are available in other grades of alloys and stainless steels. There is a full line of trim materials to match any service, and optional packing and gasket materials are available for a variety of service conditions.
