Test Rig for Flashback Arrestors : Test Rig 722

• single device for full range of functional tests
• saves costs of external testing services
• enables compliance with statutory proof-testing requirements
• prevents unnecessary disposal of older devices "on suspicion" and thus premature replacement
• option: clamp 743 with set of various adapters

Flashbacks, dirt and external damage may affect the flow capacity and proper functioning of Flashback Arrestors and Non-Return Valves.
Therefore, annual testing of all safety elements is imperative to avoid hazardous situations.

Benefits

• helps to save money- no more costly services by testing companies required
• ready for immediate and flexible use e.g. during breaks
• only one test rig for all flashback arrestors and non-return valves (up to DN 50)
• only one test rig for all 5 tests
• easy and time-saving operation
• clear readings
• robust design
• maintenance-free

Option Clamp 743

• for convenient testing
• quick exchange of test units saves time and money
• connector sets for different fittings included in package

Tests:
The following tests can be carried out:
1. leak tightness to atmosphere
2. test of non-return valve against low and high back pressure
3. operating pressure of pressure sensitive gas cut-off valve
4. measurement of flow capacity of flashback arrestors

Components:
a) regulator adjustment
b) pressure gauge
c) U-tube for measurement of leak rates
d) flow meter to control the flow
e) selector switch for operation mode
