DBB FIG 145-UHMW, 40-MM, and 50-PS
The Fabricast DBB FIG 145-UHMW, 40-MM, and 50-PS are highly engineered, high performance, double gated polymer lined knife gate valves. Serves as both a double block and bleed valve and a line blind. Designed and tested to MSS SP61 and ASME B16.5 Specifications.
- Heavy duty fabricated ASTM A36 Carbon Steel Body, Packing Gland and Yoke. Sizes up to 48”
- 6 piece replacement polymer liners. UHMWPE (ultra high molecular weight polyethylene is standard)
- The dual seat inserts are a “T” shape that mechanically locks them to the liners
- The liners and seat inserts are sealed to the valve body with a special silicone sealant preventing the flow media from coming in contact with the valve body
- The full length body liners support the gate throughout the full stroke, preventing deflection and premature packing wear
- The packing chamber in the valve body is extra deep, utilizing several rows of braided packing, resulting in a superior atmospheric seal
- In the bottom center of the body, between the dual gates, is a drain and plug
- 304 Stainless Steel fixed liner retaining rings are standard full port design, or can be made to match any pipeline I.D.
- 150 PSI CWP rated – higher pressure rating available
- ASTM A240 Dual 304 Stainless Steel gates fully machined and surface ground.
- All edges are chamfered to extend packing life and to provide a superior atmospheric seal.
- Manual valves are provided with a 4:1 ratio bevel gear operator
- Mechanical lockouts are standard – manual and actuated valves.
- Braided Teflon synthetic packing is standard 3-11 PH rating.
- Locking fasteners are standard on all Fabricast valves.
- Easily adapted to pneumatic and hydraulic cylinder or electric motor operator (no welding required)
