| The fine threads of the needle cock permit excellent adjustment for precise control of flow. The flow is restricted in both directions and is adjustable from 0 to the equivalent flow of a 0.025" diameter orifice. The 7-turn adjustment needle valves manufacturers are available in two models, the standard model and the fine adjustment model. The standard adjustment model has a pin angle of 6° with 10-64 threads; the fine adjustment model has a pin angle of 4° with 10-80 threads. |

The needle valve manufacturer can be used to control mini-cylinders, atomisers, timing circuits, filling heads, bleed vents, and in many other applications. The cock is also available with options such as a panel mount thread and a knob for easy adjustment. Maximum inlet pressure is 300 psig.
Features:
• The needle valve allows precise flow adjustment due to 56 threads per inch adjustment and three degree taper of the needle.
• The adjusted flow remains stable even during temperature fluctuations as the needle and valve seat are both manufactured from stainless steel.
• The valve body (elbow or tee) swivels 360 degrees to facilitate installation and orientation.
• The needle valve body is available with “built-in-barbs” which saves space and reduces cost of connections and assembly time. Call factory for details.
• The valve controls flows from 0 to 1 SCFM at 50 psig.
• The metal to metal industrial seal provides positive shut-off to 25 in Hg.
Material: Brass, 303 or 316 stainless steel body; all models have 316 stainless steel needle, 303 or 316 stainless steel stud and cap, stainless steel lock nut and optional brass knob. |

The F-2822 Series Needle valves are ideal for instrumentation and industrial applications. The fine angle of the needle allows for the precise control of flow, which is restricted in both directions. The Needle Cocks are adjustable from 0 to the equivalent flow of a 0.025” orifice and can be provided for inline installation or panel mounting.
Two models are available: The standard glass filled nylon model is available with straight ports for 1/16” I.D. tubing or barbs for 1/16” and 1/8” I.D. tubing. The glass-filled polypropylene model is beneficial for those applications where chemical resistance is a concern.
Both models can be supplied with a nickel-plated brass or stainless steel needle. The needles are available with a bolting slot adjustment or knurled knob. Buna-N, Viton, or Ethylene Propylene o’rings are available. |

Badotherm’s manifold range are constructed out or bar stock and forged materials in stainless steel AISI316 as per ASTM A276, A 182 and as per ASME SA 182 and SA 479. The complete valve consist of a body stem system and a bonnet assembly.
•One-way needle valves, straight or angle type, up to 5-valve manifolds
•Direct and remote executions and as monoflange.
•All our cocks are available with different kinds of stems for
o High pressure applications
o High temperature applications
o With hard or soft tip
o Variety of exotic materials: Hasteloy, Monel, Duplex, and super Duplex.

KOFLOC 2204
The KOFLOC Variable Primary Pressure Flow Controller MODEL 2204 SERIES is a control valve for precise control of minute gas flow and maintaining constant flow under fluctuating primary pressure (inlet), provided the secondary (outlet) pressure remains constant. This characteristic makes it a must-have preliminary cock in many flow control mechanisms. Constructed using high precision parts, the design of the MODEL 2204 SERIES transforms the rotation of the regulating screw to into linear motion of the industrial 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 supply pressure fluctuations
APPLICATIONS
♦ Scientific instruments
♦ Environmental analysis
♦ Atomic absorption spectrometry
♦ Gas chromatograph
♦ R&D
♦ General industrial use |
