The Fabricast FIG 61 is a unique high performance knife gate valve design utilizing dual replaceable polymer seals. Designed and tested to MSS SP81 and ASME B16.5 specifications.
Features
- Dual Polymer seals (Teflon is Standard) fitted on 316 Stainless Steel retaining rings along with robust o-rings (EPDM Is Standard 300 Deg F.) that provides resiliency and seal loading. The o-rings also seal the machined retainer ring cavity in the valve body to eliminate external leakage. Seals, o-rings and retainer rings are easily replaced either in the shop or in the field.
- Full Port
- Bi-directional Drip Tight Shutoff.
- 150 Psi CWP Rating.
- Heavy Duty Cast CF8M 316 Stainless Steel Body and Packing Gland.
- Valve body, retaining rings, stem and Polymer seals are precision CNC machined.
- ASTM A240 316 Stainless Steel gate fully machined and surface ground to provide a smooth sealing surface for the seals. All edges are chamfered to extend packing life and provide a superior packing seal.
- Heavy Duty Cast CF8 304 Stainless Steel Yoke, Stemnut Retainer and Stem Clevis.
- 14″ and larger valves are provided with a ball bearing yoke bushing to reduce handwheel rimpull.
- Braided Teflon Synthetic Packing is Standard 3-11 Ph Rating.
- Cast WCB Steel Handwheel (weldable).
- Easily adapted to Pneumatic Cylinder, Hydraullic Cylinder, Spring Cylinder, 3:1 and 4:1 Bevel Gear, Lever And Electric Motor Operator (no welding required). Note: not for deadend service unless a ring or blind flange is used
