4 Installation
4.1 Preparation
DANGER!
Valve not suitable for application!
The valve has product-specific characteristics, installation dimensions and connections. The use of a valve unsuitable for the appli-
cation can cause personal injury and damage to property as well as endanger the environment.
►Check the compatibility of the valve materials with the medium.
►Match the dimensions of the piping system with the valve as per the type plate.
►Make sure that the pressure rating, type of connection, and connection dimensions correspond to the application conditions.
DANGER!
Uncontrolled evasion of the medium!
If the pressure in the piping system has not been completely relieved, the medium can escape in an uncontrolled manner. Depending
on the type of medium, risk of injury may exist.
►Completely relieve pressure in the pipe before opening.
►In case of harmful, inflammable, hot or explosive medium, completely empty and flush pipe. Possible residues must be taken
into account.
►Provide for safe collection of the medium by implementing appropriate measures (e.g. connection of a collection container).
►Drain the valve with the valve in the half-open position and collect the medium.
►Hazardous medium residues may remain in the valve despite drainage.
►Wear appropriate protective equipment.
NOTE!
Incorrect storage and transport!
Improper handling can impair the functional properties and quality of the product.
►Store and transport in unopened original packing.
►Protection against harmful physical influences such as light, dust, heat, moisture, UV radiation and mechanical influences.
►Storage in open position (delivery condition).
►Inspect for general damage before installation.
►Do not remove from the original packing until immediately before installation.
►Valves with an identifiable malfunction must not be installed.

18
Operating InstructionsDiaphragm valve type 514, 515, 517, 519
4.2 Installation process
►Always install the valve in the open position.
DANGER!
Use of hazardous and non-approved media!
Non-approved chemically aggressive or hot media can attack materials, cause personal injury and endanger the environment.
Components not in contact with the medium can be attacked by leakage inside the valve.
►Observe the safety data sheets or the applicable safety regulations for the media used.
►Check the compatibility of the valve materials with the medium.
►Do not use unapproved media.
►Regularly check the valve for wear and, if necessary, perform service.
►Wear appropriate protective equipment.
►For hot media: Work only on cooled down system.
►In case of uncertainty regarding approved media, contact the GF Piping Systems sales company.
CAUTION!
Thermal expansion forces on piping system!
Preventing thermal expansion during temperature changes results in axial or bending forces. Piping system and valve may be da-
maged.
►Make sure that the forces are absorbed by suitable fixed points before or behind the valve.
CAUTION!
Damage due to increased Operating torque!
Risk of injury and/or damage to property due to the use of non-designated aids to increase the Operating torque.
►Operate the valve only with the intended actuating means (lever, transmission and actuator) according to the Operating torque
specified in the technical documentation.
►Mount the valve as a fixed point, or fasten the associated pipe directly upstream and downstream of the valve with associated
retainers.
►If increased Operating torque occurs, check valve for damage or wear.
CAUTION!
Pipe not in alignment!
Risk of injury and/or damage to property due to leakage of the piping system because of stress forces in the piping system.
►Make sure that the valve and pipe are aligned with each other.
4.2.1 Radially mountable and dismountable valve
All materials with Valve body type 514
1. Loosen the union nuts and slide them onto the intended pipe ends.
2. Depending on the type, cementing, screwing or fusing the connecting parts onto the pipe ends (see GF Planning Fundamentals
Industry - Glued/Fused connections).
3. Place the diaphragm valve between the connection parts.
4. Tighten the union nuts manually.
WARNING!
Tighten union nuts up to DN50 only hand-tight!
Risk of injury and/or material damage due to leaking liquids caused by overtightened or defective union nuts.
►Tighten union nuts up to DN50 only hand-tight, without auxiliary tools.
►Tighten the union nuts from DN50 with a strap wrench as per the tightening torque specified in the technical documentation.
4.2.2 Adhesive joint
PVC-U, PVC-C and ABS - Types 514, 515
Only join identical materials. After the curing time, flush the pipeline section with water without pressure (see chapter "Jointing
technology" in GF Planning Fundamentals Industry).

19
Operating Instructions Diaphragm valve type 514, 515, 517, 519
WARNING!
Connection of incompatible materials!
Risk of injury and/or damage to property due to leakage of the piping system because of connections of dierent, mutually incompa-
tible materials.
►Only identical materials may be joined together by means of fused and bonded joints.
►Pipeline sections with bonded joints must be flushed with water without pressure as soon as possible after the joints have been
completed.
4.2.3 Fused joint
PP-H, PP-N, PVDF, PVDF-HP - Types 514, 515, 519
Only join identical materials (see chapter "Jointing technology" in GF Planning Fundamentals Industry).
WARNING!
Connection of incompatible materials!
Risk of injury and/or damage to property due to leakage of the piping system because of connections of dierent, mutually incompa-
tible materials.
►Only identical materials may be joined together by means of fused and bonded joints.
►Pipeline sections with bonded joints must be flushed with water without pressure as soon as possible after the joints have been
completed.
4.2.4 Flange connection
All materials with Valve body type 517
For the tightening torques of the screws, refer to the relevant chapters of the GF Planning Fundamentals Industry.
CAUTION!
Leaking flange connection!
Danger of injury and/or material damage due to leaks in the piping system.
►Periodic check that no media escapes to the outside.
►If media is exiting at the flange connections, they have to be retightened.
CAUTION!
Contaminated jointing faces!
Risk of injury from contact with medium due to leaking connections.
►Protect jointing faces and connection parts from damage and poisoning, especially from hard or sharp-edged particles.

5 Putting into operation
5.1 Preparation
1. Check that it is working: Close the valve and open it again.
2. Flush piping system.
5.2 Pressure testing
The same instructions apply to the pressure testing of valves as to the pipe (see chapter "Processing and installation" in GF Planning
Fundamentals Industry).
1. Check that all valves are in the required open or closed position.
2. Fill the line system with test medium and carefully vent it.
3. Build up test pressure.
4. The valves and connections should be checked for a tight seal during the pressure testing.
5. After the successful leak testing: remove the test medium.
6. Document your results.
DANGER!
Piping system not tight!
Leaky connections can cause medium to escape and cause property damage and personal injury, as well as endanger the environ-
ment.
►Check the tightness of the connections before putting into operation.
►Periodic check that no medium escapes to the outside.
►Wear appropriate protective equipment.
DANGER!
Pressure too high!
Exceeding the maximum permissible pressure can damage the piping system, causing medium to escape and cause property dama-
ge and personal injury, as well as endangering the environment.
►The component of the piping system with the lowest PN determines the maximum allowable test pressure in the piping section.
►Take measures to prevent pressure surges.
►Wear appropriate protective equipment.
CAUTION!
Maximum permissible test pressure!
For the pressure test of valves in open position, the same instructions apply as for the piping system (max. 1.5 x PN, und max. PN +
5 bar), but the test pressure in closed valve position must not exceed max. 1.1 x PN.
►For detailed information, see the Georg Fischer Planning Fundamentals.
►After successful pressure test: Remove test medium.
►Record the results.
