Globe Stop Valve in Electric Actuator with Flange ANSI 16.5, ASTM
A216 Gr WCB
PRODUCT INTRODUCTION
Description
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 Class150~Class900 globe valves are usually
bolted bonnet design .And the Class1500~Class2500 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
graphite wounded gasket is used for Class ,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 and gear box is usually used for
globe valve actuation.Chain wheel and electric actuator can be also
used for globe valve actuation if being reguested 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
the customer.The internal surface of the stuffing box,of which area
is contacted with the packing,is of excellent finish(Ra 3.2um).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 compactness(Ra 0.8um)and ensure the reliable tightness
of the stem area.
Belleville spring loaded packing impacting system
If 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 our globe valves have the back seating design.In 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 API,it is not
advisable 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 usually forged steel.The
sealing surface of the seat is spray welded with hard alloy
specified by the customer.Renewable threaded seat is used for
NPS<10 globe valve,and welded on seat can be also optional if
being requested by the customer.Welded on seat is used for
NPS>12 carbon steel globe valves.For stainless steel globe
valve,intergral seat is usually adopted,or to weld hard alloy
directly intergrally.Threaded or welded on seat is also optional
for stainless steel globe valve 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 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.
