The Brand, Series 83 is a two port, non-adjustable, pressure compensated, inline flow control, with free reverse flow. The amount of flow is determined by the diameter of the orifice in the compensator piston. The spring and piston are held in place when it is connected to an #8 SAE male fitting. This flow control is inexpensive and gives the customer the ability to change the flow rate by swapping the piston with another that has a different size orifice.

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

KOFLOC 2412/2412M
The KOFLOC Precision Needle Valve MODEL 2412 SERIES is designed to control minute flows with precision and ease, controlling minute flow stably and accurately, as low as 0.5 ML/MIN. It has been widely used in numerous applications from general industrial applications to analytical equipment such as AAS (Atomic absorption spectrometer). The needle orifice of the MODEL 2412 SERIES has a temperature compensating structure (US P.A.F.) achieving the characteristic of 0.3%/˚C for gas temperatures between 15 ˚C to 35˚C. MODEL 2412 SERIES includes 15 different needle valves to offer optimum flow control corresponding to various flow levels MODEL 2412M SERIES with Multi-Dial is a precision needle valve with a radial gauge to give simple means to approximate flow volume
FEATURES
♦ Accurate control of minute flow
♦ Wide needle variation
♦ Non-rotating needle
♦ Wide operating temperature range
APPLICATIONS
♦ Atomic absorption spectrometer
♦ Burn control
♦ Research and development
♦ Air sampler
♦ Filter testing
♦ Burn control
(2412M)
♦ Can be used as a substitute for a flowmeter
♦ Detection of flow pass resistance fluctuations

Description:
The SLV Series Signal Lock Valve provides protection in the event of pneumatic instrument signal loss caused by failure of RTU, I/P transducer, pneumatic controller, or other signal generating devices. In the event of instrument signal failure, the SLV-30 will maintain the last position of the control valve and positioner. The Becker SLV-30 can be factory installed or easily retrofit to most existing pneumatic positioner models.

Pressure controls serve various functions, which may be divided into control and protection functions. Examples for control functions are compressor cycling, pump-down or defrost control. Protection functions include, pressure limiting and cut out against excessive pressures, against loss of charge or for freeze protection.
Our pressure controls are equipped with display scale and pointers to indicate the approximate settings. The display scales are printed in relative pressure units "bar" and "psi". For precise setting of the controls, external gauges must be used.
