Ansi Globe Valve
Design and Manufacture:Cast steel globe valve to BS 1873 and ASME B16.34;Forged steel globe valve to API
602.
lnspection and Test:API 598.
BW end dimension:ASME B16.25
Socket-weld dimension:ASME B16.11
Face to face and end to end:ASME B16.10
Pressure-temperature ratingsg:ASME B16.34
Actuation
Hand wheel impact hand wheel& gear box is usually used for globe valve actuation.Chain wheel and electric
actuator can be also used for globe valve actuation if being requested by the customers.
Gasket of fCover Flange
Stainless steel+lfexible graphite wounded gasket is used for Class 150and Class300 globe valve,Stainless
steel+flexible graphite wounded gasket is used for Class600,and ring joint gasket is also optional for
Class600,Ring jointg asket is used for Clas900 globe valve,Pressureized seal design is used for Class
1500-Class2500 globe valve.
Packing Seal
STONELEIGH engineering serviceswww.stoneleigh-eng.com
Molded flexible graphite is used for packing material.PTFE or combined packing material can be also used if
being reques ted by the customer.The internal surface of the stuffing box.of which area is contacted with the
packing,isof excellent finish (Ra 3.2μm)The stem surface,contacting with the packing,should be rolled and
pressed after being precisely Machined,so as to reach to the high finish and com-pactness(Ra0.8μm) and
ensure the reliable tightness of the stem area.
The features of globe valve
Bolted Bonnet;Outside Screw and Yoke;Rising Stems;Metallic seating surfaces.
Stem Design
The stem is of integral forged design,The minimum diameter of the stem shall per the standard requirement.
Belleville Spring Loaded Packing lmpacting System
lf being requested by the customer,the Belleville spring loaded packing impacting can be adopted for
enhancing the durability and reliability of the packing seal.
Back Seating Design
All ur globe valves have the back seating design.ln most Cases,the carbon steel globe valve is fitted with a
renewable back seat,For stainless steel globe valve,the back seat is machined directly in the bonnet or is
machined after welding.When the globe valve is at fully open position,the sealing of the back seat can be very
reliable.However,as per the requirement of API600,it is not a dvisable to add or change packing by the mean of
back seating when the valve is pressure containing.
Seat
For carbon steel globe valve.the seat is usualy forged steel,The sealing surface of the seat is spray welded with
hard alloy specified by the customer.Renewalbe threaded seat is used for NPS≤10 golbe valve,and welded on
seat can be also optional if being requested by the customer,Welded on seat is used for NPS≥12carbon steel
globe valves.For stainiess steel globe valve,integral seat is usually adopted.or to weld hard alloy directly
integrally.Threaded or welded on seal is also optional for stainless steel globe valve if being requested by the
customer.
Stem Nut
Usually,the stem nut is made of ASTM A39 D2,lt is also can be made of copper ally if being requested by the
customer.For large sized globe valve,rolling bearing is fitted at the two sides of stem nut in order to minimize
the open and close torque of the globe valve.
Special Globe Valve
Besides the common globe valves,we also makes cryogenic globe vavle,bellow sealed globe valve,Jacketed
globe vavle,etc.
