2. Body and Bonnet Connection
Pressure seal bonnet design.
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.
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. Threaded or welded on seat is also optional for stainless steel globe valve if being requested by the customer.
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.
In most of cases, handwheel & gearbox is usually used for globe valve operatrion. Chain wheel and electric actuator can be also used for globe valve operation if being requested by the customers.
