Valtorc: Spring Return Fail Safe Automated Knife Gate Valves

Valtorc spring return knife gate valveValtorc's spring return cylinders are available in 316SS, carbon steel Epoxy ends and can work with knife gate valves up to 20". The spring return linear cylinders can be designed "Man Safe" captured springs. This means the unit can be easily dismantled and repaired on site without special equipment.

As standard the spring return cylinders are welded shut to prevent tampering and accidental removal of the end caps.

The captured spring design can be easily removed, is safe, heavier and more expensive. However, our welded end design is cheaper, lighter, more compact and able for non-field repair.

The spring options are available in spring to close or spring to open.

The back-up systems are bulky and rely on complicated accessories which can fail. The Valtorc spring return cylinders are more robust and more compact.

Check-All Valve: Vacuum Flange Insert

Check All Vacuum Flange InsertCheck-All Valve Mfg. Co. is proud to introduce the brand-new Vacuum Flange Insert (VI) for your rough to high vacuum systems, systems requiring frequent cleaning or modification, roughing and foreline plumbing, and research and teaching lab applications among others. The VI is designed to fit between ISO/NW/KF/QF vacuum flanges designed in accordance with DIN 28403, DIN 28404, ISO 1609, and ISO 2861. It is both a centering ring and a check valve therefore, requiring no additional space in the line. Its size makes it extremely economical when compared to full-bodied check valves. The VI can also be used as a low-pressure relief valve under either positive or vacuum conditions by using the desired spring setting.

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.
