Sizes Range: From 1/2” up to 14”
Pressure Ratings: Up to 600 Lb
End Connections: Flanged, BW, SW, THR
Operator: Lever, Gear, Bare Stem
Double Gland Adjusting Design
One gland (nut & stud) provides adjustment of compression of stem seal packing, and another gland (nut & stud) provides adjustment of plug into sleeve. These two adjustments can be separatley operated, which assure the seal ability of stem, plug, and minimize the operation torque.
Trunnion Plug Design
Incorporating the plug rotating in the sleeve locked in the bottom of the body protects the PTFE sleeve from deformation, being scaled by the plug under high pressure and high temperature, which can effectively avoid the leakage of plug.
Weidouli’s Trunnion type plug valve incorporates a plug rotating in a PTFE sleeve locked in the body, this is our independant research and development if patented products.
Live Loaded Belleville Spring
The self-adjusting function of belleville spring, utilized in nut & stud of double gland, provides a constant, uniform pressure on the stem packing and plug. This is especially important when pipe pressure and temperature is anomaly.
Advanced Stem Threefold Sealed Design
Primary Sleeve Seal: The primary stem seal is around the circumference of the plug. Flow media is prevented from reaching the stem.
Secondary Wedge Gasket Seal: The secondary backup seal system prevents high pressure and leakage of medium, especially when the pipe pressure is anomaly.
Tertiary V-Shaped Packaging Seal: V-Shaped PTFE packaging prevents point movement with compression and sealing failure with uneven pressure. Flexible graphite incorporated with metal diaphragm for high temperature and high pressure is available on request.
Packing Box Design
The packing box is machined between the valve body and bonnet, can completely isolate the flow media from the bonnet, achieve the valve cover material dropped from a special material to stainless steel, and reduce the cost.
Plane Bearing
Plane bearing under the plug gland can minimize the operation torque and easy operation, which reduce friction and eliminate shaft binding.
Compact and Robust Body Design (one-piece body)
Adopting the integral body configuration instead of separated, especially on the button cover, avoids the leakage of these points.
Fine Tuning of the Angel Plug
The angel of the plug is changed from 4 degrees into 6 degrees, to extend the length of the seal.
