Adjustable Needle Valve NFCC Specs

The document summarizes a needle valve model NFCC from Sun Hydraulics. It has a maximum flow rate of 7 gpm and works at pressures up to 5000 psi. It uses a handknob or screw adjustment to control flow through a fully adjustable orifice from fully closed to a maximum diameter of 0.19 inches. Various seal materials are available including Buna-N, EPDM, Viton and Polyurethane.

TECHNICAL FEATURES
All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge
extension dimensions from the mounting surface may vary.
Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure
differential across ports 1 and 2.
A balanced adjustment mechanism allows for easy adjustment even at high pressures.
The sharp-edged orifice design minimizes flow variations due to viscosity changes.
The flow path through this valve is bi-directional. The preferred path is port 1 to 2, to allow interchangeability with other flow controls.
There is no leakage when the adjustment mechanism is turned to the shut-off position.
Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage
the seals.
