This website answers most questions about Heating System Boiler Controls on central heating systems to aid in troubleshooting, inspection, diagnosis, and repairs.

The NT Series Coal Valve was designed for long term reliability and performance – produced with a hardened (AR600 equivalent) steel blade. The NT Series Coal Valves can be used not only to control the coal mass to the burners, but also to control the coal velocity to the burners. Improper coal velocity can lead to coal layout, pipe fires or ...

NOTE: These air operators are only for use with two-way and three-way diverter style valves. Click Here to Learn More about HiP Ball Valve Actuators ...

Alibaba offers 1,052 air coal valve products. About 44% of these are valves. A wide variety of air coal valve options are available to you, such as casting, stainless steel, and brass.

Valves with 3 ports; inlet, outlet (cylinder) and exhaust. They are generally used to operate spring return cylinders or as pilots for larger diaphragm or piston operated valves Small 3 Way Valves Air flows up to 1.2 Cv Large 3 Way Valves Air flows from 1.5 Cv and higher

The Adjustable Orificing Valve is designed to provide a variable orifice in an existing fuel piping system to help correct pulverized fuel/air flow imbalance between burners due to pipe routing and mill outlet characteristics. The Adjustable Orificing Valve consists of two opposed gates that operate by rotating a single handwheel.

The coal originated from the West Kentucky No. 13 (Baker) coal seam which is associated with the Illinois coal basin. The plant feed was comprised of over 60% rock which was the target for eject and thus provided a greater challenge for the air valves to recover between events.

Pneumatic Directional Air Control Valves - Industrial ... Compressed Air Preparation High-quality filtering, control, and lubrication – all the components and accessories you need for reliable compressed air preparation. ... AVENTICS supplies pneumatics at the press of a button.

Coal Slurry Pipelines. The very first application for Red Valve Pinch Valves was on the world's first coal slurry pipeline. Today, more than 50 years later, coal handling remains a popular application for many Red Valve Pinch Valve products. Crushed coal can be transferred by pipeline when water is added, creating a coal slurry.

Throttle valves, shut-off valves and slide gates, hand operated or actuated, allow you to regulate airflows or control your bulk goods handling. Connecting components; ... Air flow control gates (for air pipelines only) Air bleeds. Adjustable blank-off covers. Pipe regulator gates. Pipe regulators, hand-operated.

Air Coal Valves. The Stock Air Coal Valve (ACV) is a double rack and pinion style valve used as a means of isolation below a feeder. The air-tight body provides positive shut-off to minimize hot air and gases from entering the feeder during maintenance.

The Air Separator is designed to reduce noise The Air Separator is designed to reduce noise and wear on system components improve system efficiency and operation and ensure fewer call backs. It collects micro bubbles and static air from the system where it is separated from the liquid and is released through a vent. It features a heavy ...

Our rotary airlock valves are used in a wide range of applications where there is need to minimize system air loss while transferring material between vessels with differing pressures. They are used as feeder valves to meter the flow of material between vessels with equivalent pressures. You will also find them doing double

valve was manufactured with high pressure hub ends with clamps to enable the customer to easily remove the valve for repair. This eliminates having to cut two very thick welds, rewelding and post weld heat treating. These four, 2-inch GEN-X MOGAS ball valves are handling cold reheat isolation in a coal-fired plant. Setting the Standard

Our initial order was for the world's first coal slurry pipeline, where we created the only available valve capable of reliable slurry control. Red Valve is the largest manufacturer and supplier of pinch and check valves, and is the preferred supplier for municipalities and industrial plants worldwide.

These valves are also used for the isolation of material feed downspouts located between the pulverizer and feeder, allowing safe access and maintenance of the feeders without exposure to dangerous hot gas. Stock® Knife Gate Valves are designed for adverse conditions. They are made to handle high velocity mixture of air and pulverized coal.

aiRFlex® is a low cost pinch valve solution that doesn't compromise quality or function. The non-stretch aiRFlex® design increases elastomer tube life 2 to 3 times over conventional air-actuated pinch valves. aiRFlex® is ideal for all liquids and powders in low-pressure applications.

Located in Elmhurst, Illinois, Val-Matic Valve & Manufacturing makes quality valves for municipal and industrial applications.

Mining Industry Valves. The mining industry is traditionally a heavy user of RF pinch, slurry and tailings handling valves because of the highly abrasive nature of metal concentrates. We have proven success using our air release valves in this same environment in slurry and tailings applications as well as leaching processes.

ASCO brings together the ASCO & Numatics product lines to be the worlds leading manufacturer of solenoid valves, pneumatic valves, cylinders & actuators, air preparation products & related accessories.
