GENERAL DESCRIPTION

651511 Extrusion

651511-1 Airless Spray

Automatic Valve with the following features.

The ball and valve seat are made of tungsten carbide for maximum resistance to erosion and wear.

The (3) 90565 packings are made of PTFE for maximum wear and resistance to solvents.

This unit has a 2” diameter air cylinder. The 72842 piston is made of Buna “N”.

It has a 1/2” mounting hole.

Both air inlets are 1/8 - 27 NPTF (female).

Air operated opening and closing.

OPERATING INSTRUCTIONS

Use only genuine ARO® replacement parts to assure com- patible pressure rating and longest service life.

HEED ALL WARNINGS.

WARNING HIGH PRESSURE DEVICE. Improper usage of this equipment could result in serious injury. The possibility of injection into the flesh is a potential hazard. Never allow any part of the human body to come in front of, or in direct contact with, the material outlet. An injection injury can be serious. If injection should occur, contact a qualified physi- cian for immediate treatment of such injuries.

SERVICING. Before servicing or removing fluid hose or valve from a unit that has been used, be sure to disconnect air lines and carefully bleed pressure off of the system.

PREVENT FIRES. When pumping, flushing or recirculating volatile solvents, the area must be adequately ventilated.

Keep solvents away from heat, sparks and open flames. Keep containers closed when not in use.

CAUTION The maximum working pressure for the auto- matic dispensing valve assembly is 5000 p.s.i. (345 bar).

With proper care, this unit will give long reliable service. To maintain this performance, it should be “flushed thoroughly” with solvent immediately following each application period if equipment is to be idle for a long period of time.

If material leakage occurs between valve housing (25) and body (19), check gasket (24).

If material leakage occurs at orifice of gun, check ball and ball seat for dirt or foreign substance. Inspect ball and ball seat (23).

If material leakage occurs around piston rod (21) in open- ing of air cylinder head (13) check tightness of retainer (15) or worn packings (17).

If air leakage occurs around the air cylinder, check for damaged or worn “O” rings. (Indicated on the drawing (12), (11), and (4)).
