Victaulic: Series 713 Swing Check Valve Line

Victaulic Series 713 Swing Check Valve LineVictaulic has extended the size range of its Series 713 swing check valve to include 2- to 4-inch (50 to 100 millimeter) sizes. The additional sizes enable the grooved-end check valve to be used on a wider range of high-pressure piping systems, offering operators quick, simple installation and maintenance.

The Victaulic Series 713 swing check valve offers higher working pressures than previous designs for greater versatility. Designed for headers that feed upstream facilities as well as other high-pressure services, the valve can be used in applications requiring Class 300 pressure ratings. The 2-inch (50 millimeter) valve is rated to 1,000 psi (6,895 kPa), while the 2½-, 3- and 4-inch sizes (65 to 100 millimeter) are rated to 750 psi (5,170 kPa).

Curtiss-Wright: Changeover Valve from Farris Engineering

Curtiss Wright Changeover Valve from Farris EngineeringCurtiss-Wright’s Industrial Division has launched a new changeover valve from its brand family of Farris Engineering.

Designed in conjunction with their sister business, Phönix, and sold under the Farris name, the optimized change over valve is a three-way globe valve used in combination with Farris pressure relief valves wherever a shutdown cannot be tolerated. Changeover valves enable pressurized systems to be equipped with dual relief devices, allowing for maintenance to the relief devices without interrupting system overpressure protection. For critical services, a second change over unit can be added at the outlet of the relief valves allowing for collection of toxic or aggressive effluent into a closed collection system.

The changeover units were designed according to the appropriate industry requirements, including ASME B16.34 BPVC, ISO40126, API 520.2, EN19, and AD 2000 A2. The COV is offered with metal seating, Model 320B, or an optional bellow sealed stem, Model 370B, for toxic or lethal service. Optimized flow through the valve is guaranteed regardless of design. The optimized interior flow path results in a lowered deflection angle and reduced pressure loss within the COV. The result is less than a 3% pressure drop to the COV outlet or active PRV inlet.

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.
