When installing the fitting, the operator or the person responsible for the design of the installation must ensure that applicable national regulations are complied with. The manufacturer reserves all rights to make technical changes and improvements at any time.
The use of these installation and maintenance instructions assumes that the user is qualified to ‘Qualified Personnel’ level.
Operating staff must be given appropriate training in the operating and maintenance instructions.
2 SAFETY
Please also read through these notes carefully.
2.1General potential danger due to: a. Failure to observe the instructions b. Improper use
c. Insufficiently qualified personnel
2.2Correct use
2.2.1 Area of application
Neoseal valves are fittings that are used for the isolation, throttling and regulation of corrosive and non-abrasive liquids, together with gases, pastes and powdery products in pipelines, vessels, apparatus etc.
The area of application of the fitting is the responsibility of the system designer. Special characteristics of the fitting must be taken into account.
A very wide selection of product-wetted components parts is available which allows suitable combination for the optimal solution to your specific application.
Always consult the manufacturer when the fitting is to be used with media that require or preclude the use of certain materials.
2.2.2 Method of operation
The valve is opened or closed by turning the flap spindle. The angle of rotation is 90°.

2.2.4 Usage restrictions
The product-wetted components must be classified as resistant to the product to be conveyed. Refer to appropriate literature or consult the manufacturer or distributor for advice on this.
2.2.5 Modification prohibition
Mechanical modifications to the valves or the use of other manufacturers’ parts for repair purposes is not permissible. Safety is not guaranteed if this requirement is disregarded. Repair work must only be carried out by the manufacturer’s trained personnel.
2.2.6Warning about foreseeable misuse
Valves and their accessories (e.g. operating elements) must not be misused as climbing aids.
2.2.7Duty to comply with the instructions for operation, maintenance and servicing
These instructions form part of the delivery package and must be kept clean and made accessible to the user.
2.3 Sources of danger
2.3.1 Chemical external
The valve body has a 2-part polyester coating. The coating can be attacked externally by strong solvents, leading to corrosion of
the body. If damage of this nature occurs, the effects of the environment should be investigated and the damage to the coating made good.
2.3.2 Mechanical
When using the hand lever, it should be ensured that there is still sufficient clearance for the hands at the end position of the handle, so that there is no risk of trapping.
Excessive oscillation and vibration should be avoided, to prevent the bolts loosening.
2.3.3 Electrical
If static charges can lead to explosions, the valve must be earthed by means of the earthing accessory and mount it to the valve by using the screw on the valve body neck. In addition, we recommend the use of valves with electrically conductive linings. Please contact your supplier!
2.3.4 Thermal
Due to the range of operating temperatures between -40°C and +200°C, surface temperatures from -20°C to over +85°C can be present on the valve body. Suitable precautions should be taken to protect against burns due to high or freezing temperatures. In particular, insulated gloves should be worn when using the hand lever, for example.
In case of fire, the mechanical strength of the PTFE ring bellows is no longer guaranteed above 200°C.
2.4 Requirements for the operator
This means people who are familiar with the erection, installation, commissioning, operation and maintenance of the product and have appropriate qualifications relating to their activities and functions, such as e.g.:
-Instruction in and duty to comply with all installation-related, regional and internal works regulations and requirements.
-Training or instruction in accordance with the Safety Standards for personal care and use of appropriate safety equipment and protective workgear, like e.g. personal protection
equipment (e.g. insulated gloves), suitable for the operating conditions.
Furthermore, these people must have read and understood these instructions.
3 TRANSPORT/STORAGE
The valve is supplied with protective covers. Do not remove the protective covers until immediately prior to installation. They protect the PTFE surface from dust and mechanical influences.
3.1 Transport
-Transport temperature -20°C to +65°C.
-Protect against external force(impact, shock, vibration).
-Do not damage the coating.
3.2 Storage
-Storage temperature -20°C to +65°C, dry and dust-free.
-A drying agent or heating is required in damp storage areas to protect against condensation.
-Keep the valve disc in a slightly open position (5-10°).
3.3 Handling prior to installation
-With versions with protective covers, only remove the covers immediately prior to installation!
-Protect against the effects of weather, e.g. dampness (or else use a drying agent).
-Proper treatment prevents damage.
