MT 162 is used for pressure testing of various types of valves and fittings. The unit can be used to test if the valve opens and closes easily under pressure, and if the housing and seals can withstand the test pressure. A manually operated piston pump draws water from the storage tank, fills the valve interior, and generates the test pressure. A manometer indicates the test pressure. The welded-in collector tray is fitted with a ball valve to drain. The valve under test is attached to a mounting flange and sealed by a blank flange. The piston pump and mounting flange are interconnected via a pressure hose. The test stand includes its own storage tank so it can be operated independently of a water pipe supply. The tank must be topped up occasionally.
  The test stand is used in particular for the final testing of the valves assembled and disassembled in the GUNT MT 154, MT 156, MT 157 and MT 158 assembly projects series. This ensures that a successfully completed assembly project can be examined for operability with a formal test procedure.

The following experiments can be conducted together with valves and fittings, such as a wedge gate valve or angle seat valve (MT 156), butterfly valve or non-return valve (MT 157), ball valve or shut-off valve (MT 158) 
- correct connection of valves to a flange coupling
- familiarisation with the terms "nominal pressure"

  and "test pressure"
- performing the final test for the GUNT MT 154,

  MT 156, MT 157 and MT 158 assembly projects
- checking the free movement of the valves and
  fittings 
- pressure testing
  * leak testing of housing and flange seals
  * leak testing of the valve seat
- drafting a test report
