Twist Sleeve Flow Control

CAD Model


Description: The Beswick MIL-FC contains an adjustable orifice and check valve. The orifice meters flow in the forward direction, while the check valve permits free return flow. This valve is particularly well suited for control of small bore air cylinders. The o-ring seals fit to make the valve insensitive to vibration preventing inadvertent changes to the setting.

Max Pressure Rating: 200psig

Effective Orifice: The maximum effective orifice should be selected from the options below (0.011”-0.055”, or 0.28-1.4mm), based on the approximate maximum flow needed in the application. All configurations are adjustable down to a fully closed bubble-tight shut off.

Adjustment: The knurled sleeve rotates 360 degrees and is restricted from sliding axially. An O-ring is fitted into an eccentric cavity within the valve, in the same plane as the radial inlet orifice. This O-ring is pressed against the radial inlet orifice when the valve is closed and becomes free of the hole as the sleeve rotates.

Approximate Weight: 16g in brass and 303 stainless. Weight will vary slightly, depending on configuration.

Porting: 10-32 external threaded inlet and 10-32 internal threaded outlet ports.

Seal Material: Buna-N
