| Variable Flow Control Valves maintain the flow rate of hydraulic fluid to a selected value. Applications include hydraulic cylinders requiring constant extension or retraction speeds and hydraulic motors requiring constant rotational speeds. When used with a fixed delivery pump the excess flow is By-Passed across a relief valve. |

The miniature Preset Flow Control is ideal for many applications involving pneumatic systems, including the control of cylinder speed.
The operation of the flow control is based on the movement of a small disc. The flat surface on one side of the orificed disc seals and permits flow through the orifice. The amount of flow permitted in the reverse direction is determined by the orifice size. In the forward direction full flow is permitted. The flow controls design allows a maximum supply pressure of 75 PSI with a minimum cracking pressure of less than 10” H2O. Orifice sizes are available from .004” to .040”. |

| B&G Flo-Control Valves are used for preventing gravity flow in forced water systems and to permit summer-winter operation of indirect water heaters. Flo-Control Valves in NPT sizes ¾" to 2" are made in combination straight-angle patterns permitting installation in either horizontal or vertical pipe lines. Larger sizes may be furnished in either straight or angle patterns. Removeable top cap allows easy cleaning and service without removing pipe connections. Manual operating position for vertical lift disc to permit gravity circulation. |

KOFLOC 2203
The KOFLOC Variable Secondary Pressure Flow Controller Valve MODEL 2203 SERIES is a control valve for precise control of minute gas flow and maintaining constant flow under fluctuating secondary pressure (outlet), provided the supply pressure remains constant. This characteristic makes it a must-have preliminary valve in many flow control mechanisms. Constructed using high precision parts, the design of the MODEL 2203 SERIES transforms the rotation of the regulating screw to into linear motion of the needle without subjecting it to gaps and vibrations produced by the screw, to ensure stable and even control of minute flow.
FEATURES
♦ Excellent flow stabilization
♦ Clean construction
♦ Independent from secondary pressure fluctuations
APPLICATIONS
♦ Gas chromatography
♦ Environmental analysis
♦ Atomic absorption spectrometry
♦ Gas mixing
♦ R&D
♦ General industrial use |

The PCD Series Digital Dual Valve Pressure Controllers are designed for applications that require a precise pressure control device with easy to integrate features specifically for dead ended applications. The PCD series pressure controller provides an RS-232 and a choice of analog output of the pressure signal as a standard feature. Alicat's P series standard digital pressure gauge electronics are integrated with two proportional control valves (a feed valve and an exhaust valve). The PCD series device was designed for applications that have a closed volume or are dead ended.

The PRS6 is a three-way pressure reducing valve that has been developed to give reduced pressure in a particular part of the hydraulic system. The valve maintains the secondary pressure setting constantly, regardless of pressure variations on the primary side. Common applications include pilot circuits in hydraulic and electro-hydraulic servo systems.
Compact and easy to install
Easy to adjust within respective pressure range
Can be factory set and sealed to prevent unauthorized pressure changing
Highly suited for use as a reducing valve in pilot circuits where the pilot pressure is taken from the main circuit |
