Severe service valves are offered in several standard designs, including non-return, isolation and control types.
When planning a check valve installation, the primary goal is to achieve a valve and piping system that offers the longest service life at the lowest cost.
Because natural gas is currently considered a good source of energy for both environmental and economic reasons, it’s growing in use.
Most valve end users are already using smart valve positioners on some control valves, but they may not have time to check the valve diagnostics software to notice if any valves are developing problems.
One of the most important components of an automated threaded stem valve is the ubiquitous stem nut, a relatively simple and unsophisticated mechanical device that converts the rotary motion of an actuator into the linear stem movement needed to open or close one of the many types of gate valves or sluice gates.
Knife gate valves are more commonly installed vertically, so why might a knife gate be positioned horizontally?
A common practice in process services is to use manual globe valves with hand wheels for regulating flow.
Check valves, as critical as they are for flow system performance, often don’t receive the respect they are due, said Arie Bregman, vice president and general manager, DFT, Inc., in a recent VMA presentation.
Stop check valves are vital to several industries to protect boilers and other equipment.
Knife gate valves are used to provide isolation in various applications including oil sands slurries, pulp stock, waste water and power generation.
Normally, valves are pressure tested by the factory to check for leaks before they’re shipped.
For over 100 years, preventing catastrophic failure in the process control industry has been a continuously evolving area of study.
The valve landscape has changed over the past few decades—instead of über-high volumes of simple valves, many buyers and makers of valves are increasingly aiming for low-to-medium volumes of complex, high-precision valves made from exotic materials.
Most professionals in the valve industry are already familiar with the use of linear actuators to operate globe valves.
With valve components sourced from numerous suppliers around the globe, valve, actuator and control manufacturers are faced with a significant number of challenges while attempting to meet the desired flow control at a competitive price.
The Series 300 Plunger Valve from Henry Pratt Co., a subsidiary of Mueller Water Products, is designed to reduce cavitation and stagnant water creation to help water systems improve operational safety, efficiency and flow control.
Conval now offers an easy to retrofit, single-weld, OSHA-compliant safe vent drain for its Clampseal Y-pattern forged globe valves.
SPIRAX SARCO has released a new range of lift check valves, LCV3 (Cast Iron), LCV4 (Carbon Steel), LCV6 (Stainless Steel) and LCV7 (SG Iron) suitable for most industries.
ITT Engineered Valves introduces the Fabri-Valve 33 PTA push-through slurry valve.
Tyco Flow Control, a unit of Tyco International, has expanded its Anderson Greenwood instrument valve line to include the new M30 series primary isolation instrumentation root valve.
Straight pattern globe valves are widely used in the oil and gas industry to regulate and control the flow of fluids.
With the discovery of oil and gas in water depths thousands of feet below the surface, selection of valves is more important, difficult and complicated.
Conval, a global leader in high-performance valves for the world’s most demanding applications, offers over 12,000 configurations of Clampseal® Y, angle and T-pattern globe valves.
CAMERON’S ENTECH DRV-BN nozzle check valve was designed to provide three mandatory requirements of a check valve: non-slam, low-pressure drop and virtually no maintenance in large-diameter applications.
SPIRAX SARCO introduces the CVS10 sanitary check valve designed specifically to prevent reverse flow conditions and reduce the risk of cross contamination within the pharmaceutical and high-purity industries where critical design factors such as high surface finish, full material certification and drainability are of paramount concern to end users.
ATI actuators are piston-style linear actuators used on control valves, gate valves and other rising stem valves.
Flowserve Corporation, a leading provider of flow control products and services for the global infrastructure markets, announced the availability of Flowserve Multi-Z anti-cavitation control valves in a new cast globe body.
