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.
