Lined Valve Company: Tips for Trouble-Free Knifegate Valve Packing Replacement

Safety first - release pressure from the valve, make sure it is closed.

  1. Remove packing gland nuts and bolts.
  2. Raise gate to full open position.
  3. Pull up the packing gland to the top of the gate and secure it to the top of the gate.
  4. Using a packing hook or screw driver, remove all the old packing.
  5. Carefully clean the packing box.
  6. Using a pre-cut packing kit, insert packing one row at a time into packing box. Tap down each row of packing into place using a flat bar tool. Packing joints should be located 180° apart.
  7. Pull packing gland down and tighten nuts and bolts using cross torque method. DO NOT OVERTIGHTEN.
  8. Bring valve up to working pressure and tighten the packing gland enough to stop any leaks or drips. Over tightening of the gland will result in reduced packing life.  

DFT: Axial-Flow Check Valve

DFT Axial-Flow Check ValveDFT Inc. announces the release of its new BNC™ Check Valve, a nozzle-style, axial-flow check valve specifically designed to excel in high-pressure applications.

Many natural gas companies and other industries are now placing their pipelines below ground and are looking for a one-piece valve they can weld in and bury. The BNC™ Check Valve answers that demand with a precision nozzle-style valve that uses axial-flow technology to eliminate turbulence and prevent erosion and vibration. This design reduces downtime and maintenance costs and boosts capacity and accuracy.

Additionally, this valve provides a critical service to the power industry because the valve’s one piece body eliminates leak paths, while providing tight shut off.
