4 Inch Flange Globe Valve Stainless Steel Wcb Manual Corrosion
Resistance
Globe valve, also known as shut-off valve, is the most widely used
valve. It is popular because of the low friction between the
sealing surfaces during the opening and closing process, which is
more durable, the opening height is not large, the manufacturing is
easy, and the maintenance Convenient, not only suitable for medium
and low voltage, but also for high pressure. The closing principle
of the shut-off valve is to rely on the pressure of the valve rod
to make the sealing surface of the valve disc and the sealing
surface of the valve seat closely to prevent the medium from
flowing.
The valve plays an important role in cutting off and throttling the
medium in the pipeline where it is located. As a very important
shut-off valve, the valve is sealed by applying torque to the valve
stem. The valve disc exerts pressure to make the valve disc sealing
surface and the valve seat sealing surface closely fit to prevent
the medium from leaking along the gap between the sealing surfaces.

Features:
1. Generally
Bolted Bonnet: Outside Screw and Yoke;
Rising stems;
Metallic seating surfaces
2. Body and Bonnet Connection
Bolted bonnet;
3. Bonnet Gasket Style
Stainless steel + flexible graphite wounded gasket;
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
the customer.
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 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
reliable.
