2. Body and Bonnet Connection
Class150 globe valves are usually bolted bonnet.
3. Bonnet Gasket Style
Stainless steel + flexible graphite wounded gasket is used for
4. Packing Seal
As usual, flexible graphite is used for packing material. PTFE or
combined packing material can be also used if being requested by
5. Stem Design
The stem is of integral forged design. The minimum diameter of the
stem shall per the standard requirement.
6. Backseat Design
All our globe valves have the backseat design. In most cases, the
carbon steel globe valve is fitted with a renewable backseat. For
stainless steel globe valve, the backseat is machined directly in
the bonnet or is machined after welding. When the globe valve is at
fully open position, the sealing of the backseat can be very
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. For Stainless steel globe valve,
integral seat is usually adopted, or to weld hard alloy directly
8. 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, if the rolling bearing is fitted,it is effective
to reduce the torque of globe valve for easy operation.
In most of cases, handwheel & gearbox is usually used for globe
10. Other Globe Valves
Besides the common globe valves, we also makes cryogenic globe
valve, Bellow sealed globe valve, Jacketed globe valve, etc.
