INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS TYPE BV50
Storage & Protection
1.
Before storage always inspect the package for damaged or missing items upon delivery.
The valves have to be stored with the gate in open position.
The connections must be covered to protect the flange faces and internals for dust, dirt, oil or other
impurities.
Store the valves indoors at a cool temperature between -10°C and 30°C in a dry place that is fire
resistant, weather tight and well-ventilated. No corrosive chemicals should be present.
When an electric- or pneumatic actuator is mounted on the valve we recommend that is should be
cycled approximately every 60 days.
Any spare parts for the valve shall be stored in the original packaging and under the same conditions
as the valve is stored.
For storage longer than 4 months, the storage container should be inspected every four (4) months to
ensure it is in good condition, and any additional protective coverings or materials are in working
order. Ensure all parts are plugged, and bare metal is covered with a suitable rust inhibitor.
Avoid storage under direct sun exposure.
Do not stack unpacked valves.
After a long-term storage clean the valve, especially the sealing surfaces and check the valve's
tightness before installation.
Do NOT toss the valves and do NOT lift them by the handwheel, gearbox, ,actuator or gate guards.
Do NOT lift the valve by the valve bore, this can damage the seating surfaces and the seals.
For lifting fix two or more eyebolts into the threaded mounting holes of the valve body or wrap soft
straps tight around the body to lift the valve.
Use lifting equipment rated for the weight of the valve assembly.

For proper operation the valves must be undamaged and free of foreign material, please pay special attention that the valve cavities are clean.

Installation Procedures Tests and inspections of the open and closed valve are necessary to see if there is any trouble to open/close the valve. Prior to installation the pipeline must be cleaned from dirt and welding residues to avoid damage of the valve during operation.
- Page 4 IOM BV50 / 20131107 Also these installation positions are acceptable. Please keep in mind to install the valve in the way that the pressure pushes the gate against the seat, respecting the arrow on the body. ALWAYS USE SUPPORTS when the shafts deviates more than 30°...

All the valve parts for replacement shall be the same as the original ones in size and material. Only use the original Belven spares to replace the parts in the valve. Don’t let the valve remain disassembled in the work shop, it can only higher the risk of dirt entering the valve or corrosion of the metal parts. - Page 8 IOM BV50 / 20131107 Make sure the system is depressurized and cooled down Use appropriate personal protection equipment (gloves, safety shoes, etc). Shut off all operating lines to the valve and place a warning sign. Isolate the valve completely from the process, release process pressure and drain the process fluid from the valve.
