Control for electropneumatic valve banks
01 June, 2008Camozzi pneumatics has introduced an input module to its series Y electropneumatic valve banks which gives advanced control and sensing.
Inline progressive start valve
01 June, 2008A progressive start valve allows air pressure to build up slowly to a machine when the air supply is turned on. This allows any actuators that have either been moved or have fallen due to gravity when air was removed to move into position at a controlled speed.
Pilot-operated safety relief valves
01 June, 2008The F7000/8000 range of pilot-operated safety relief valves come with stainless, carbon steel construction, snap and modulating action pilots and complies with ASME Code section VIII.
Pressure measurement in liquid chemicals
18 January, 2008The Wika Hydral-Line pressure measuring instruments are designed for use in liquid chemicals distribution applications. It has been adapted to the special requirements of the process equipment and UHP chemicals distribution systems.
Glandless spool
11 December, 2007Most pneumatic solenoid valve manufacturers provide solenoid valves with nitrile seals. The seals are either in the form of O-rings, disc seals or bonded to the spool then surface ground. Over the years, nitrile seals have proved satisfactory. In addition to nitrile (soft seal) valve ranges, Norgren produces a range of ISO Standard valves with 'glandless spool' technology. The glandless valves use a hardened anodised teflon-coated spool and sleeve. The glandless spool and sleeve have no dynamic seals. The spool operates on an air bearing principle that offers several benefits over conventional nitrile soft seal valves. The spool and sleeve are hardened to 62-70 Rockwell C.
Swing check valves in thermoplastic
14 November, 2007Praher Valves has expanded its range with the new-generation K4 Swing Check Valve in PVC, PP, PPGF (polypropylene glass filled) and PVDF.
Conveyor valve
14 November, 2007SMC has released its series VFD direct operated poppet valve for use in zero pressure accumulation conveyor systems. When incorporated with a conveyor system's control logic and sensors, the valve controls the air pressure that is used for roller actuation and roller braking, creating space between products on the conveyor line.
ISO standard valves
13 July, 2007The Norgren five-port valves can now incorporate twin 3/2 valves in the valve body, effectively having two three-port valves in a five-port body yet still conforming to ISO 15407. This enables water treatment plants to control twice as many spring return actuated process valves in an ISO valve. For example, 20 activated valves could be controlled by 20 3/2 solenoid valves that are mounted in a 10 station valve island. Alternatively, a combination of twin 3/2 valves and standard 5/2 valves can be configured enabling double acting activated valves to be controlled.
Butterfly valves
18 June, 2007The Series ABFV automated butterfly valves are suitable for use in chemical and wastewater applications with a 316 SS disc and choice of EPDM, Buna-N or fluoroelastomer liner. The valves are designed with direct mount electric or pneumatic actuators for a compact valve package.
Solenoid valves for micro-dispensing
13 June, 2007The Lee VHS series micro-dispense valve is a high-speed (1200 Hz), two-way solenoid valve designed for applications that require micro- to nano-litre dispense volumes.
Emerson opens technology centres in China
07 June, 2007Emerson Process Management, an Emerson business, has opened two technology centres in Tianjin, China, to help meet the rising demand for control-valve and valve-automation products for the growing process manufacturing industry in the Asia-Pacific region.
Swing check valve
15 May, 2007Praher Valves' K4 Swing Check Valve in PVC, PP, PPGF (polypropylene glass filled) and PVDF is suitable for applications involving water and most chemicals, up to 10 bar pressure.
Adjustable gate valve lockout
15 May, 2007Brady Australia has released an Adjustable Gate Valve Lockout. This device eliminates the need to buy three or more gate valve lockout devices as it is capable of adjusting to fit multiple size gates. The design ensures that the gate valve is completely enclosed, for greater worker safety and tamper prevention.
Diaphragm control valve
20 March, 2007The pneumatically operated plastic body type 2730 diaphragm valve comprises hermetical separation of fluids from the operating mechanism by the diaphragm, and is rated for use with potable water and for sterile to aggressive applications.
Angle seated valve
14 March, 2007The Tanair range of angle seated valves and actuators is constructed of 316 stainless steel and are spring return as standard.
