Technical Specification

Design and Manufacture:Cast steel globe valve to BS 1873 and ASME B16.34;Forged steel globe valve to API 602.

Inspection and Test:API 598.

End flange dimension:ASME B16.5

BW end dimension:ASME B16.25.

Socket-weld dimension:ASME B16.11.

The features of globe valve

Bolted Bonnet;Outside Screw and Yoke;Rising stems;Metallic seating surfaces.

Body and Bonnet Connection

The body and bonnet of Class 150~Class 900 globe valves are usually with studs and nuts.And the body and bonnet of Class 1500·Class 2500 globe valves are usually of pressurized seal design.

Gasket of Cover Flange

Stainless steel +flexible graphite wounded gasket is used for Class 150 and Class 300 globe valve;Stainless steel+flexible graphitewounded gasket is used for Class 600,and ring joint gasket is also optional for Class 600.Ring joint gasket is used for Class 900 globe valve;Pressurized seal design is used for Class 1500~Class 2500 globe valve.

Actuation

Hand wheel,impact hand wheel &gear box is usually used for globe valve actuation.Chain wheel and electric actuator can be alsoused for globe valve actuation if being requested by the customers.

Packing Seal

Molded flexible graphite is used for packing material.PTFE or combined packing material can be also used if being requested by thecustomer.The internal surface of the stuffing box,of which area is contacted with the packing,is of excellent finish (Ra 3.2 μm).Thestem surface,contacting with the packing,should be rolled and pressed after being precisely machined,so as to reach to the highfinish and compactness (Ra 0.8 μm)and ensure the relizble tightness of the stem area.

Belleville Spring Loaded Packing Impacting System

lf being requested by the customer,the Belleville spring loaded packing impacting system can be adopted for enhancing the durabilityand reliability of the packing seal.

Back Seating Design

All our globe valves have the back seating design.In most cases,the carbon steel globe valve is fitted with a renewable back seatFor stainless steel globe valve,the back seat is machined directly in the bonnet or is machined after welding.When the globe valveis at fully open position,the sealing of the back seat can be very reliable.However,as per the requirement of APl,it is not advisableto 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 usually forged steel.The sealing surface of the seat is spray welded with hard alloy specifiedby the customer.Renewable threaded seat is used for NPS≤10 globe valves,and welded on seat can be also optional if beingrequested by the customer.Welded on seat is used for NPS≥12 carbon steel globe valves.For Stainless steel globe valve,integralseat is usually adopted,or to weld hard alloy directly integrally.Threaded or welded on seat is also optional for stainless steel globevalve if being requested by the customer.

Stem Design

The stem is of integral forged design.The minimum diameter of the stem shall per the standard requirement.

Stem Nut

Usually,the stem nut is made of ASTM A439 D2.it is also can be made of copper ally if being requested by the customer.For largesized 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 Gate Valve

Besides the common globe valves,Company also makes cryogenic globe valve,Bellow sealed globe valve,Jacketed globe valve etc.
