Installation; Maintenance - IMI TA 60 Anleitung

English
General
The TA 60 valves are classified within the Pressure Equipment Directive (European Parliament
and Council directive 2014/68/EU) with the consistency level as set out in the table 1.
TA 60 valves are shut-off valve intended for heating, refrigeration and tap water installations.
(Fluids in group 2 according to the directive).
Marking
The valve housing is marked with the following data:
TA: Manufacturer
Material according to table 2
DN according to table 3 (* with reversible flanges)
Max. permitted pressure PS (PN) according to table 3
Valve type: 60, 61, 64 respective 68
CE-marking according to table 4 and year of manufacture
In addition to that stated on the valve housing, a max. permitted temperature of 170 °C applies.

Installation

The valve should be kept in a dry, clean location and protected from damage and contamination.
Before you install the valve, check that:
• the valve is clean and undamaged.
• the pipe system has been cleaned.
Valves with female threads
Install the valve according to defined industry standards.
Valves with flanges
Before installing the valves check that:
• counter flanges are parallel and the sealing surfaces are clean and undamaged.
• flat seals are in accordance with the given standard for flanges and that they are centred
correctly.
Lubricate the threads on the bolts and fit washers. Tighten the bolts crosswise using a torque
wrench to the tightening torque set out in tables 5 to 6.
Pressure switch and thermostat
In order to guarantee the lowest and highest pressure as well as to ensure that the temperature is
not exceeded the system should be fitted with a pressure switch and thermostat.
Exception: The pressure may be exceeded when pressure testing, max 9 bar (PN 6), max 24 bar
(PN 16) respective 37.5 bar (PN 25).
Commissioning
Test the pressure on the valve using cold water.
Let the valve remain fully open while the system is flushed clean.
Tighten the flange joints and check for leakage in connection with commissioning.

Maintenance

The TA60 valves are maintenance free under the condition that they are used within their normal
application area. If leakage should occur from the inner stern the gland nut should be tightened a
little.
