Conval: Clampseal Blowdown Service Valves

Conval tandem blowdown valveConval offers Clampseal Blowdown Service Valves to provide necessary control for continuous or tandem boiler or turbine blow down and bottom blow-off service.

For continuous service, blowdown valves are available in ¾” through 4” sizes with butt or socket weld and flanged ends, in ASME/ANSI Class 900 through 4500. Standard materials are Low Alloy SA 182-F22, SA-182-F91 or SA-105. Specials are available upon request.

For tandem service, blowdown valves are available in ¾” through 4” sizes with butt or socket weld and flanged ends, in ASME/ANSI Class 900 through 4500. Standard materials are Carbon Steel A105, Low Alloy F22 or F91.

Clampseal blowdown valves are fully serviceable in-line using standard Conval tools. The valves feature a uniform one-piece gland, which eliminates the potential for stem damage from gland cocking. With leak-proof bonnet, the cartridge-style packing chamber allows rapid access to valve trim for inspection and maintenance. The pressure seal fixed backseat provides maximum valve integrity by ensuring a positive internal stop for the valve and stem and disc assembly. This also securely isolates the packing from line pressure when the valves is fully open, to increase packing life.

Weir Valves & Controls USA: Atwood & Morrill Forged Gate Valve

Weir Atwood Morrill Forged Gate ValveWeir Valves & Controls USA Inc. (WVC USA) is pleased to announce the introduction of the Atwood & Morrill Forged Gate Valve. WVC USA recently manufactured four forged valves that were ordered for installation at a new-build combined cycle plant in the Southeast U.S. - scheduled to go online in 2019.

Customers of combined cycle power plants have indicated that Type 91 gate valves have been experiencing shorter than anticipated life cycles. These valve bodies are traditionally cast in A217 C12A material. Based on customer feedback and industry research, WVC USA put together a dedicated project team to develop a product designed to tackle this specific customer problem. Forged valve bodies help minimize material defects and provide better quality and longer life valves, especially at elevated temperatures with thermal cycling conditions.

Mueller Water Products: Class 250/300 Resilient Wedge Gate Valves

Mueller Class 250300 Resilient Wedge Gate ValvesThe expansion of Mueller’s 350psi, AWWA/UL/FM rated resilient wedge gate valve (RWGV) product line with new end design conforms to the ASME/ANSI dimensional requirements for Class 250/300 valves. Specifically, the flange and lay length (end-to-end) of the new Class 250/300 RWGV complies with ASME/ANSI B16.1, B16.42, B16.10, and PN25 drilling standards. This ductile iron valve is available in standard sizes from 3 to 12 inches, complies with the requirements of AWWA C509/C515 and NSF 61/372, and retains all competitive features of other 350psi rated RWGVs including integrated lift lugs, a self-activating wedge seal and grade 316 stainless steel fasteners.

Typical applications include mechanical rooms of high-rise buildings, pump stations, reservoirs, and water processing facilities that operate at higher pressures. Class 250/300 RWGVs are available in non-rising stem (NRS), post indicating (PI), and outside screw & yoke (OS&Y) configurations, in both Mueller® and U.S. Pipe Valve & Hydrant® brands.

Victaulic: Refuse-to-Fuse Series 906 KGV

Victaulic Refuse to Fuse Series 906 Knife Gate ValveVictaulic has launched its new Refuse-to-Fuse™ Series 906 Knife Gate Valve (906 KGV), the industry's first in-line maintenance KGV for HDPE pipe. The new valve simplifies installation and maintenance, reduces downtime and improves worker safety.

The 906 KGV for HDPE pipe is ideal for fluid lines containing solids or abrasive materials common in mining, wastewater treatment, power generation and other industrial settings with applications such as slurry and tailings lines or cyclones.

The new valve also improves worker safety because only one component has to be replaced versus removing the entire valve from the pipeline. This first-of-its-kind, revolutionary design eliminates the need for rigging with heavy chains and pulleys swinging over the heads of maintenance crews.

DFT: Model TLW Axial Flow Wafer Check Valve

DFT Model TLW Axial Flow Wafer Check ValveDFT Inc. releases its new TLW® Check Valve, a Tapped Lug Wafer style silent check valve specifically designed for use in horizontal and vertical installations for liquid, gas, and steam applications where exposed bolts are not suitable.

This check valve was designed for use in a refining industry application but is relevant for any industry where bolts are required not be exposed to fire or corrosion. As with all other DFT check valves, this silent check valve reduces the potential for reverse flow and water hammer and is designed for long life and low maintenance.

Standard trim materials include a stainless-steel seat, disc, and bushing (optional soft seat seal available). The valve can be installed either horizontally or vertically and is compatible with steam, water, and gaseous media. Custom sizing is available for low flow applications.
