PET COCK
CONSTRUCTION: STAINLESS STEEL
Pressure Rating: 150 PSI
Sizes: 1/8”, 1/4”, 3/8”, 1/2” NPT

THROTTLER FOR REDUCING PULSATION
CONSTRUCTION: BRASS, TYPE 303 STAINLESS STEEL

MODEL EFI 130.jpg
MODEL EFI 129.jpg

Pressure Rating: 600 PSI (Brass)
                              2000 PSI (Stainless Steel)
NPT Connection: 1/4” male inlet and
                                 1/4” female outlet

The throttler employs the variable restricted orifice principle–the entrance for pressure can be made larger if the pressure medium is of high viscosity or smaller when the pressure is high and the frequency of pulsation great. Adjustment of the variable orifice is accomplished by means of an eccentric which is activated by a thumb screw. A locknut protects the adjustment from vibration or inadvertent change.
