Type D Pilotair directional control valves A custom valve for a standard price, the D Pilotair is easily tailored to your installation. The operators and valve segments can be rotated at degree increments to fit most any application problem, with flows of 2. SuperSpool directional valves This electronic volume meter accurately measures volume flow rates. A selectable output electrical signal of Hz, VDC or mA is proportional to the flow rate measurement.
Maximum operating pressure is psi. Three sizes are available with flow ranges up to 1 Cv.

Type M Plus pressure control valves Designed for short-distance up to 50 feet , low-force pressure control applications, this valve offers economical and accurate control. Operators include hand lever, foot pedal and mechanical plunger. Maximum supply pressure is psi, with choice of two controllable output pressure ranges, or psi. Flexair pressure regulating valves The Flexair valve gives 3-way, precise control of the various functions performed during the opeation of oil drilling rigs, excavating machinery, hoists, dredges and production machines.
Handle options include various lengths, self-holding, selfreturning, and detent in extreme positions. Handle guide arrangements are available to operate one, two or three pressure or directional control lines separately or in combinations.
Maximum pressure is psi. Type H Controlair valves Hand, foot or mechanically operated, these valves can control both pressure and flow of air. Some models control functions in separate and independent air circuits or in branches of the same circuit.
Other models control these functions either selectively or simultaneously in three separate and independent branches of an air circuit.
Outlet pressures are controllable between psi, and can maintain pressure within 1. Applications for our mobile cylinders include transmissions, positioning hydraulic valves, clutches, brakes, rail car hopper control, etc.
We were the pioneer in the field of pneumatic remote controls for marine propulsion systems. Today, we provide both pneumatic and electronic controls for a broad spectrum of vessels, from pleasure and fishing boats, to tugs, offshore supply and military ships.
Air logic valves and accessories A wide variety of other special marine components are available to complete installations.
These include shuttle, check and flow control valves, gage blocks, timers, positioners, multifunction valves and pressure regulators. Marex OS electronic marine control systems Type C linear positioners These diaphragm-lever actuators have a power rating of in-lb-degrees and come in four pressure range choices up to 90 psi. These powerful diaphragm-lever type actuators have a force rating up to in-lb-degrees. Single and two-direction models are available, as well as models with a separately controlled stop cylinder.
A-3 actuators The compact A3 actuators are single direction, piston actuated positioners. Positioning can be linear with the A-3L model, with a force rating of 12 lb through.
Radial positioning is obtained with the A-3R, rated at in-lb-degrees. Operating pressure is psi. In the past, each crane broke down at least three or four times a day due to a failed valve. Alumina oxide is taken into compressed air, which jammed the old valves.
Valves fail primarily from high contamination of the compressed air. The raw products of alumina oxide and fluoride are taken into the compressed-air system and delivered to the valves.

These products are abrasive, corrosive, and found in abundance throughout the plant. South Missouri along the Mississippi River has a hot and humid climate.
That means the compressed air carries a high level of moisture nearly year round. To make the situation even worse, the plant is more than 40 years old, with compressed-air lines producing pipe scale that ends up in pneumatic components.
The pipe scale alone can make ordinary air valves fail regularly.
Due to the volume of air used, the high contamination levels, and the compressors being on board the crane, filtering the air becomes impractical due to high cost and added maintenance. Although air filtration was tried, the maintenance crews found the air filters clogged up quickly and became inoperable in short order. The extreme contamination makes it virtually impossible to filter the air economically. The answer B.
Burks, the maintenance supervisor over the pot lines, was looking for a solution. He tried different internal valve materials and configurations, special seals, and air filtration in an effort to enhance valve performance. None of these worked out.
This valve does not use a spool or a poppet, but rather sliding ceramic plates to control the air flow direction. The Ceram valve uses sliding ceramic plates to control the air flow direction, allowing it to operate in harsh conditions.
The ceramic plates offer many advantages over spool valves. Because ceramic material is very hard, contamination has no effect on the plates. The design uses two ceramic plates placed one on top of the other. A ceramic-to-ceramic seal is formed where the plates fit together, thus eliminating any clearance for contamination to lodge like that found in spool or poppet valves—and ultimately avoiding jamming.

Contamination passes through large slots in the ceramic plates and is either delivered to the cylinder or exits through the valve exhaust ports without getting a chance to jam the valve. On top of that, there are no elastomeric seals in the critical area of the valve to wear or become damaged by the contamination. The combination of ceramic plates, a ceramic seal, and an extra strong return spring makes for a very robust valve that will operate reliably under the most contaminated conditions.
His goal was to reduce some of the failures that cause so many problems.
Burks thought if he could find a valve that would work for two or three days without failing, it would immensely improve his difficult situation. After one week of operation, Burks was asked how the valve was performing.
IMTS 2012: Ceram™ pneumatic valves now available through GoTo program
The ceramic-plate technology survives the contamination, survives the heat, and withstands the harsh and abusive conditions inherent on the pot lines. He began replacing all of the jackhammer valves with the Ceram valve, completing the task after two weeks.
The company is enjoying very large cost reductions not only from the labor savings, but from the elimination of valve replacement costs. Because the Ceram valve has yet to fail, maintenance teams are now free to engage in preventive, predictive maintenance instead of reactive maintenance, which is a very important goal for Burks and his team.
This helps keep the plant running more efficiently, reduces costs, and improves morale of the maintenance teams. Morale is up also with the crane operators. They say their jobs can be done more efficiently, because the cranes no longer need to be taken out of service thanks to the Ceram valves, which work every time.

Burks was asked if he could describe in one word the biggest benefit the Ceram valve has brought him so far. Reliability of the cranes has improved significantly. The result was immediate.With around years of expertise in pneumatics, Aventics employs over 2, associates worldwide. The ceramic plates offer many advantages over spool valves.
Available for 2-position double solenoid and air Spring return valves.
R : auxiliary press. Maximum internally piloted valve pressure is psi. It requires the use of large and complicated equipment, heat, chemistry, manpower, and a huge amount of know-how. Paseo de la Reforma , Esquina Niza Deleg. Ports are M5 After the subbase has been replumbed, remove the valve from the subbase and remove the bottom gasket as shown in Figure 1 and 2.
