Description
Class 200 WOG Stainless Steel Gate Valve Threaded
Class 200 WOG Stainless Steel Threaded Gate Valves are designed for on/off isolation in compatible piping systems where corrosion resistance and dependable shutoff are required. The valve uses a 316 stainless steel body, screwed bonnet, solid wedge disc, and non-rising stem configuration.
This valve is designed to ASME/ANSI B16.34, tested to API 598, and rated for 200 PSI working pressure at 350°F. The supplied product information also identifies hydrostatic shell test values of 300 PSI and 220 PSI. Country of origin is Taiwan.

Gate Valve Operation
A gate valve controls flow by raising or lowering an internal wedge-shaped disc through the flow path. When fully open, the disc is moved out of the primary flow path. When closed, the solid wedge seats to isolate the line.
This valve is intended primarily for fully open or fully closed service rather than throttling applications.
The threaded-end construction allows installation into compatible threaded piping systems without welded or flanged connections.

Valve Construction
316 Stainless Steel
- 316 stainless steel construction
- Provides corrosion resistance for compatible media
- Suitable for a range of commercial and industrial environments
- Useful where stainless steel piping components are specified
- Verify media compatibility before use
Solid Wedge Disc
- Solid wedge gate design
- Designed for positive isolation
- Moves vertically through the flow path
- Used for open/closed service
- Not intended primarily for flow throttling
Non-Rising Stem
- Stem does not extend significantly upward as the valve opens
- Useful where vertical clearance is limited
- Compact operating envelope
- Handwheel operates the internal gate mechanism
- Different configuration from a rising-stem gate valve
Screwed Bonnet
- Threaded bonnet-to-body connection
- Compact valve construction
- Supports access to internal valve components
- Common gate-valve body configuration
- Refer to the manufacturer cut sheet for construction details
Non-Rising vs. Rising Stem Gate Valve
Non-Rising Stem
- Stem remains relatively fixed vertically during operation
- Requires less clearance above the valve
- Useful in compact piping installations
- Valve position may be less visually apparent from stem height
- Used in this VGT102 valve design
Rising Stem
- Stem rises as the valve opens
- Provides a visible indication of gate position
- Requires additional vertical clearance
- Common in many larger gate-valve applications
- Different operating configuration from this valve
Standards & Testing
ASME/ANSI B16.34 Design
- Valve design identified to ASME/ANSI B16.34
- Applies to pressure-containing valve construction
- Provides a recognized valve design standard
- Review manufacturer documentation for complete details
- Use within published service limitations
API 598 Testing
- Valve testing identified to API 598
- Applies to valve inspection and pressure testing
- Supports verification of valve pressure integrity
- Manufacturer cut sheet provides product-specific information
- Confirm project testing requirements before installation
Pressure & Hydrostatic Test Ratings
The supplied product information identifies this valve with a 200 PSI working pressure rating at 350°F.
It also lists a 300 PSI hydrostatic shell test and a second 220 PSI hydrostatic test. The supplied text labels both as shell tests, so the exact distinction between these two test values should be confirmed against the VGT102 manufacturer cut sheet.
Common Applications
Commercial & Mechanical Piping
- General piping isolation
- Water-service piping
- Utility piping
- Equipment isolation
- Threaded piping systems
Industrial Service
- Process piping isolation
- Maintenance shutoff points
- Compatible liquid-service applications
- Corrosive-environment applications where 316 stainless steel is suitable
- Systems requiring full open/full closed valve operation
Installation & Selection Guidance
- Confirm the required nominal valve size before ordering.
- Verify threaded connection compatibility with the mating piping.
- Use the valve primarily for fully open or fully closed service.
- Do not rely on a gate valve as a precision throttling valve.
- Verify that the 200 PSI at 350°F working rating is suitable for the intended service.
- Confirm media compatibility with 316 stainless steel and all internal components.
- Use an appropriate thread sealant for the system media, pressure, and temperature.
- Apply thread sealant according to the sealant manufacturer's instructions.
- Use appropriate valve wrenching surfaces during installation.
- Avoid excessive installation torque that could distort or damage the valve body.
- Allow adequate clearance for handwheel operation and maintenance.
- Confirm pressure and temperature requirements before installation.
- Installation should comply with applicable piping codes and project specifications.
