The Robertshaw I-1284-P, Q, S & T Series Temperature Regulators are compact, self-contained and self-powered, three-way control valves especially adaptable to control of water and lubricating oil temperatures on internal combustion engines. The POWER PILL® element, located inside the poppet assembly, responds to the temperature of the medium surrounding it and provides the force necessary to position the poppet as the temperature of the liquid passing through the valve changes. Temperature regulation is achieved by the proportional action of the three-way valve which varies the amount of medium through or bypassing the cooler to maintain the desired temperature. Operation of the POWER PILL elements is unaffected by pressure changes in the system.

The POWER PILLS are factory-set for the specified control temperature and are not manually adjustable. By exchange of POWER PILL elements, the operating temperature may be changed in a very simple manner. Since all internal parts lift out with the valve bonnet, it is not necessary to remove the valve from the piping. The I-1284 series is equipped with a quick-acting manual operator which permits overriding the thermal element if and when abnormal load conditions are encountered in the system. 

Operation: With low temperature liquid surrounding the POWER PILL, the poppet is in the upward position which connects ports "E" and "B." As the temperature increases, the POWER PILL stem extends forcing the poppet downward. When the temperature reaches the control point of the regulator, the valve will be at mid-stroke. If the temperature continues to increase, the poppet will continue to move downward until the by-pass port (B) is completely closed off. 

On the Robertshaw I-1284 a manual crank is provided to override POWER PILL control. Turning the crank counterclockwise moves the poppet upward to close the "C" port. The "B" port may be closed by turning the crank clockwise. In event of power pill failure, the crank should be turned clockwise until the desired cooling is achieved. 

The Robertshaw I-1284 may be installed indoors or out, provided the liquid to be controlled does not freeze. Temperature regulators should be installed as near as possible to the unit being controlled, and a pipeline strainer should be installed upstream.

Coax Valves for Flow Control

Coax Valves from Anderson-Bolds

For over 45 years, the coaxial valves developed by our company have formed a tried and tested element in the control of vacuums and gaseous, liquid, gelatinous, abrasive, contaminated, and aggressive media.

The coaxial valve design allows - as compared to conventional valves - high pressure media to be controlled at high flow rates. Our coaxial valves are available in 2/2 way or 3/2 way versions with threaded or flanged connections. The valves are actuated either by direct-acting solenoid or externally controlled.

high cycle life

fast actuation

compact design

maintenance free

Parker valves, 204/209/304/309 Series

Parker Solenoid Valves

Parker Fluid Control Division, manufacturers of the Skinner and Gold Ring lines of solenoid valves and the Sinclair Collins line of process control valves, has introduced an integrated coil for its Series 204 and 304 solenoid valves. Featuring easy installation, the integrated coil is the latest in the division's list of flexible production options for these small yet powerful solenoid valves.

The patent-pending NEMA 4X coil with rotating conduit hub permits easy installation. The valve lines also include interchangeable AC and DC coils as well as a tab coil for flexible production possibilities. Both the Series 204 and 304 also feature a complete line of high-temperature watertight coil designs to meet the most demanding environmental conditions.

The Series 204 (two-way) and the Series 304 (three-way) are available as normally closed and normally open valves. Maximized flow rates are delivered through orifice sizes ranging from 1/32" to 5/32". Additionally, the valve line is manufactured with 1/8" port size (NPT) connections.

The new product lines offer a family of direct-acting solenoid valves for air and liquid (including light oil) applications. These valves meet virtually all of today's commercial, industrial, mobile, instrumentation and medical market needs. State-of-the-art performance characteristics ensure a long life and maximized pressure ratings. Economy models are available for less demanding applications.

The integrated coil has been evaluated by Underwriters Laboratories and complies with the RoHS (Restrictions of Hazardous Substances) standard under the European Directive 2002/95/EC.

Solenoid Valves

Solenoid Valves come in all shapes and sizes and all means of operation. For automation needs, the solenoid valve is the valve of choice.

This will be a brief discussion of the common solenoid valve used in industry today.

A solenoid valve is a combination of a valve body the allows a media to flow through it, water, air, oil and a coil that with a voltage applied energizes a magnetic coil to move a plunger that allows the valve to either open or close. Solenoid valves can be signaled by sensors within a plant via an electrical signal thus an operation can then be achieved.

Solenoid valves come in three basic styles, two way, three way and four way valves. The Two way valves have two ports, an inlet and outlet. The valves can be either normally open or normally closed.
Normally Closed is the more common style as it requires power to open and will close in a power failure.

Three way solenoid valves are designed for operating cylinders, air operated control valves and in some cases diverting flow between two directions. 3-way valves can come in normally open, normally closed and universal operation. Universal operation requires a direct acting valve, normally a small size valve, 1/8, 1/4 or 3/8 ports.

Four way valves are also designed for operating cylinders and valves and can have two solenoids on them, one for each of the two operations.

The valves can come in different body materials, stainless steel, brass, PVC, Teflon or other. The most common is brass and stainless steel. Seals can be Nitrile, viton, neoprene, or Teflon to name the most common. The different seals have different temperature properties and corrosion resistance.

Most solenoid valves come with a NEMA 4X coil, good for washdown and submersion in water. Also available are nema 7/9 or explosion proof and DIN style connections.

Anderson-Bolds stocks valves from Parker and ASCO. We can also provide specialty valves from Valcor.

Anderson-Bolds ~ Since 1934

Anderson-Bolds has been in the heating and control business since 1934. Mr. A Anderson and Mr. E Bolds joined forces and combined lines to form the firm. The main product line was Chromalox electric heat and soon followed by ASCO solenoid vales and Fenwal Temperature Controls in 1939.

Throughout the years our goal has been to provide engineering help to our customers whether they are OEM's industrial users or other distributors. We are capable of sizing heaters or drives, providing layouts for snow melting or suggesting automation ideas with our industrial computers or HMI's.

Anderson-Bolds' sales engineers can figure wattage requirements for any heating job, process or comfort or can figure flow and or Cv for valves, solenoid valves, control valves or jet pumps. We are here to help with your problem applications to provide the correct product for the job.

Some of our product lines today are Watlow Heaters, Q'Mark Heaters, Toshiba, Fenwal, Parker Valves, Robertshaw Industrial, Meltric, Penberthy, Automatic Timing and Controls, Barksdale, Carlo Gavazzi, Jefferson Valves, Tapeswitch,  Air King Fans and Danfoss.
