BRASS ANGLE SAFETY VALVE
WITH OUTLET, FxF, PN16

BRASS ANGLE SAFETY VALVE WITH OUTLET, FxF, PN16

Brass F/F conveyed-exhaust limiting pressure valves, adjustable from 0 to 10/16 bar.

UNI EN ISO 228-1 threads: FxF
Admitted fluids gases, vapors and non-dangerous liquids.

AVAILABLE MODELS
560
: With metal seat
560TG: With rubber seat

Working temperature:
Metal seat: from -10 to + 200° C
Rubber seat: from -10 to + 70° C

Working pressures:
3/8″ => 2″ : PN16
2″ 1/2 => 3″: PN10

The article has been conceived and produced following the standard BS 5154 with regard to the wallthickness of the parts under pressure.
Moreover the check of the valve walls has been confirmed by tests in compliance with EN 12516-3.

TEST, TRIAL AND CALIBRATION

  1. Install on the trial bench the valve to be calibrated with free spouts exposed to the atmosphere.
  2. Install the manometer with class 0,6.
  3. Increase slowly the pressure at the source of the valve until you cause the start of the opening that can bevisually detected or heard.
  4. The requested value of the opening pressure is obtained by means of following adjustments, acting on thecalibration regulation plug.
  5. Once you have obtained the desired value, repeat twice the calibration control to check the reproducibility.
  6. Tighten the locking nut to avoid variations in the calibration pressure.

Maximum calibration allowed for all measures: 10 bar

ATTENTION
IF THE VALVE IS DISASSEMBLED, MODIFIED OR TAMPERED WITH, THE PRODUCER DECLINES ALLRESPONSIBILITY.
Pay attention when you install the valve, as the discharge occurs directly with no protection.
The valve has to be positioned in such a way that is not harmful to people. The 560 series valves areconveyed-exhaust pressure relief valves and not safety valves.

INSTALLATION

  1. For a proper installation, the valve has to be installed vertically, otherwise its operation is compromised;however we strongly recommend to convey the valve outlet to an exhaust unit.
  2. For thread sealing use a material compatible with the used fluid.
  3. Screw the valve on the threaded pipes, positioning the key exclusively on the special hexagonal partsuntil the valve is blocked on the pipe.
  4. Do not exert any strength on the auger.
  5. The exhaust piping has to be properly supported not to stress the valve structure; then use heavyclamps to support the pipes.
  6. If you use a pipe, it is necessary to place it in a slightly inclined position.
  7. The exhausted fluid has to be properly conveyed and deviated downwarts to prevent its return to thevalve and not to alter the calibration pressure.

MAINTENANCE

At least annually verify that:

  1. The valve has not been tampered.
  2. The valve does not present structural defects.
  3. The valve is still installed correctly.
  4. The drain hose is free and could discharge.

DISPOSAL
For valve operating with hazardous liquids(toxic, corrosive…) , if there is a possibility of residue remaining in thevalve, take due safety precaution and carry out required cleaning operation. Personnel in charge must betrained and equipped with appropriate protection devices.
Prior to disposal, disassemble the valve and separate the component according to various materials. Pleaserefer to product literature for more information. Forward sorted material to recycling (e.g. metallic materials) ordispose it, according to local and currently valid legislation taking into consideration the environment.
