Flanged Industrial Globe Valves Cast Carbon Steel WCB 2in Ansi 150LB Rising Stem J40H
Description:
A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.
Quick Details:
1. Type: WCB Flanged Globe Valve
2. OS&Y Construction, Bolted Bonnet
3. Size of Globe Valve: 2" / 2in
4. Pressure Ratings: ANSI 150LB / 150#
5. End Connections: Flanged RF, FF
6. Materials Available in: Carbon Steel A216 WCB;
7. Various trim materials are available to suit service conditions
8. Actuator: Manual, Handwheel, Gear
9. NACE MR 0175
Features:
1. General:
Bolted Bonnet: Outside Screw and Yoke
Rising stems
Metallic seating surfaces
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 Class150.
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 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 reliable.
7. 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. For Stainless steel globe valve, integral seat is usually adopted, or to weld hard alloy directly integrally.
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.
9. Operation
In most of cases, handwheel & gearbox is usually used for globe valve operatrion.
10. Other Globe Valves
Besides the common globe valves, we also makes cryogenic globe valve, Bellow sealed globe valve, Jacketed globe valve, etc.
