Globe Valve (Bolted Bonnet Type)

Globe Valve (Bolted Bonnet Type)

The bolted bonnet globe valve is a globe valve whose body cover is bolted, and a gasket or an octagonal sealing ring is installed in the middle as a seal. According to the different installation positions, the globe valve can be divided into a straight-through globe valve (T-type globe valve) and a straight-through globe valve (Y-type globe valve). Because the opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for flow regulation.

Bolted Bonnet Globe Valve

Bolted bonnet globe valve is suitable for class 150(PN10)~1500(PN250), working temperature -60℃~538℃ pipeline,using carbon steel, stainless steel and other different main materials can be suitable for various media. It can be used in tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy, and other fluid pipelines for cutting, adjustment, and throttling.

The globe valve is generally connected to the pipeline by flange connection or welding connection. The optional drive devices are: hand wheel, electric, pneumatic, etc.

Design

RAYS cast steel globe valves are designed and manufactured to provide maximum service life and dependability. All globe valve are full ported and meet the design requirements of American Petroleum Institute standard API600& 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34 .Valves are available in a complete range of body/bonnet materials and trims.

Ranges of Materials

Standard body/bonnet materials include nine grades of carbon, low alloy and stainless steel, 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.

Available Modifications For RAYS Steel Valves

Trim changes
End connection modifications
Packing and gasket changes
Operator mounting
Handwheel extensions
Pressure equalizing
By-pass
Customer specified coatings
Weld end bore changes
Oxygen & chlorine cleaning & packaging
A)Operation
Large handwheels for easy operation. alsoavaliable with gearing.motor actuators, pneumatic or hydraulic actuators for more difficult services.
B)Live Load Packing
In services requiring frequent cycling or with high pressure/temperature variations,live loading extends the service life between maintenance periods by requiring less stments. Belleville springs are employed to provide constant packing gland stress.
C)OS&Y
Outside screw and yoke. Cast steel globe valve yoke integral with bonnet for 10 & and smaller.
D)BB
Bolted bonnet, welding bonnet and pressure seal bonnet in services requiring frequent cycling or with high pressure/temperature variations.
E)End Connections
A choice of flanged, RTJ flanged or buttwelding end for piping flexibility.
F)Yoke Sleeve
Furnished in aluminum bronze to reduce operating torque. Most size furnished with ball bearing yoke sleeves.
G)Lantern Ring And Double Packing Set
Lantern ring leak-off fitting connection and double packing stack is optionally avaliable for critical services
H)Body-to-Bonnet Joint
A flat face gasket joint is used in the 150lb valves. A male and female joint is used in 300lb to 600lb valves.ring joint is used in the body to bonnet connections in 900lb & higher rated valves.
I)Disc
Plug disc is stem guided on all size. Disc has a differential angle front the seat to provide a line contact for maximum sealing. The bottom of v-port disc is fuided by the body seat ring for maximum disc stability in throttling applications, the soft teflon ring is excellent for lower temperature service where tight shut off required.
J)Seat Ring
Separate heavy duty, full ported rings for easy maintenance. Screwed or welded connection into body.
