01 September, 2011 byAlicat Scientific’s line of PC Series and PCR Series digital single valve electronic pressure controllers offer a variety of output options including 0-5 V, 0-10 V, 4-20 mA and RS-232.
Swagelok RHPS Series TBRS and TBVS low-pressure gas regulators
12 July, 2011 bySwagelok RHPS Series TBRS and TBVS model regulators are designed to provide accurate pressure control in low-pressure gas systems. One common application is accurate control of a blanketing (inert) gas in a closed tank or vessel. Installed on a tank’s inlet and outlet, the TBRS (inlet) and TBVS (outlet) regulators maintain a tank’s blanketing gas at a constant pressure.
Pneumatic actuation for dirty environments
09 June, 2011Integra Coal’s coal preparation plant, serving Camberwell and Glennies Creek coal mines in the Hunter Valley, uses an array of pneumatically actuated knife-gate valves to control coal flow to the preparation area. The company found that the two traditional methods of pneumatic actuation previously used in the plant were ineffective and inefficient.
Swagelok RHPS series dome-loaded pressure regulators
07 June, 2011 byThe RHPS series dome-loaded pressure regulators permit high flows and exhibit less droop than spring-loaded designs in controlling the pressure of liquids and gases. The dome-loaded design relies on a pressurised chamber above an elastomer diaphragm in place of a spring to operate the regulator. Depending on regulator size and configuration, inlet pressures can range to 400 bar. Regulated pressures span 0.10 to 2 bar, 0 to 70 bar, 0 to 200 bar, and 0 to 400 bar.
Hydac accumulator charging valves
07 June, 2011Hydac accumulator charging valves control the load of an accumulator within an adjustable switching range. By combining Hydac accumulators and the company’s charging valves, pumps and motors in oil hydraulic systems with differing flow demands can be designed to be smaller, saving costs and energy.
Pressure regulator selection
17 May, 2011Regulators are available in a variety of types, designs and materials of construction, and choices should be made with care.
Swagelok RHPS series general industrial regulators
28 April, 2011 bySwagelok RHPS series general industrial regulators offer accurate pressure control of pressures from 0-400 bar in gas and liquid systems, ½to 2″ sizes. RS and RSH model regulators employ either a spring-loaded diaphragm or piston as the sensing element, depending on the outlet pressure range desired.
Dwyer Series DCS/RDCS springless dust collection valves
23 March, 2011 byThe Series DCS/RDCS springless dust collection valves are suitable for use with the Dwyer Series DCT1000 and Series DCT500 duct collection timer boards. A springless design offers durability and reliability.
Noshok 100 and 150 Series mini valves
22 March, 2011 byNoshok 100 and 150 Series mini valves are small in size and are available in zinc nickel-plated steel, electropolished stainless steel and 360 brass.
Burkert 2000 Inox angle seat valve and modular block system
01 October, 2010 byThe pneumatically operated 2000 Inox angle seat valve consists of a pneumatic piston actuator and a 2-way valve body. Both parts are manufactured from 316L stainless steel and therefore can be used with media at temperatures of up to +180°C.
Burkert Type 6144 flipper solenoid valve
10 September, 2010 byType 6144 is a direct-action two- or three-way solenoid valve designed for neutral gases and liquids. Through the movement between the two end positions, the switching element (flipper) seals one of the two opposing valve seats and connects the other to the working port. This movement is caused by the solenoid’s magnetic field pushing a permanent magnet that is fixed to the flipper element.
DIY hydraulics
13 August, 2010Netherlands-based AMCA Hydraulic Fluid Power has designed a self-build modular concept for its hydraulic proportional load-sensing directional control valves. The build concept is designed to provide distributors, OEMs and end users with a flexible and cost-effective solution that will suit a wide range of applications.
SMC Pneumatics Series VXK process valve with built-in filter
12 August, 2010 byThe Series VXK process valve with built-in filter is designed to improve valve performance and to stop leakage. The unit’s integral stainless steel 100 mesh filter unit effectively removes most foreign matter in the circulating fluids thereby protecting downstream equipment as well as ensuring longer valve life.
SMC Pneumatics ZP2V suction valve units
12 August, 2010 byZP2V suction valve units are used where multiple suction cups are run off a single vacuum source. They are used to help prevent excessive vacuum leakage through the suction cups that do not correctly seat on a work piece.
Noshok needle and manifold valves with ZnNi plating
12 August, 2010Noshok valves are now available with zinc nickel (ZnNi) plating, achieving greatly improved resistance to corrosion in salt spray (fog) corrosion tests. All Noshok needle and manifold valves will now utilise this material as standard plating to withstand and endure harsh corrosive environments.
