PVME90 - Fire Valve

Dimensions in mm, weight in kg.

These specifications determine the series of manufactured sizes and types of fire disk valves PVM - 90 ø 100, 125, 160, and 200 (hereinafter valves only). They hold good for manufacture, designing, ordering, supplies, installation, assembling, operation, revision, and maintenance.

I. GENERAL

1. Description

The fire valves PVM-90 are fire barriers designed for air conditioning facilities that prevent flames, heat, and fumes from spreading from one fire cell to another at the sites of their installation. They provide fire endurance EI 90D1 and they can be used at all levels of fire safety. In addition to their elementary fire-stopping and technical function they fulfill also air conditioning function and they can be used also for air inlet and outlet with connected air doctor they can be installed separately. The connected air duct must be made of fire-resistant materials. Due to their flow properties and sizes these valves are designed for volumetric air flow rates ranging from 20 to 400 m³. h^-1.

2. Types of construction

It is convenient to build these valves in walls, ceilings, or in the air ducts.

When the temperature of the air flowing through the valve reaches 72°C ± 1.5°C, the thermal fuse melts up and the closing mechanism gets involved. The valve disk is pulled back into the valve saddle by the closing spring and remains in this “CLOSED” position, secured with the strip stop, against the opening due to accidental backlash and backfire. Gradual regulation of the air supply flowing through the valve is made possible by rotation of the valve disk.

The valves are intended for environments protected against atmospheric effects in class 3k5 as per CSN EN 60 721-3-3 standard and for explosive atmosphere of BNV class as per CSN EN 1127-1.

IV. MATERIAL, SURFACE FINISH

The valve bushing is made of zinc-coated sheet metal. The valve body and disk are made of sheet iron and the surface is coated with white baking paint RAL 9010. The closing valve disk is reinforced with an asbestos-free and fire-resistant material. The other components are made of galvanized materials.

V. CHECKING AND TESTING

Dimensions are checked by standard gauges according to the standard for non-tolerated dimensions commonly used in air conditioning technology. All components as well as principal and connecting dimensions are subject to interoperable product control according to drawing documentation. After the valve is assembled, it is subject to functional testing.

VI. PACKAGING, TRANSPORT, ACCEPTANCE, STORAGE

1. The valves are delivered in cartons with a shrink-wrap layer at the top.

They are carried in bulk by common means of transport. Upon agreement with the customer, the valves may be transported on pallets.

2. If no method of acceptance is specified in a purchase order, then taking over by the carrier shall be considered as the acceptance.

3. During manipulation at transporting and warehousing, the valves have to be protected against mechanical damage and atmospheric effects. The valves are warehoused indoors in environments free of aggressive fumes, gases, and dust.

4. During transporting and warehousing, make sure that the ambient temperature does not exceed + 60°C.

5. The manufacturer gives the valves a 24 months’ guarantee period beginning from the date of shipment.

6. Product data

The name plate with the following data is attached to the valve body:

1. firm’s logo
2. manufacturer’s name and domicile
3. technical standard No.
4. serial No.
5. fire endurance
6. size
7. year of manufacture

7. Scope of delivery

The delivery includes a complete valve as well as the certificate of quality and completeness confirmed with quality control stamp.

VII. INSTALLATION, OPERATION, MAINTENANCE, SERVICEABILITY OBSERVATION

1. Installation, operation, maintenance and serviceability observation can be carried out by the personnel with qualification for these activities - “Qualified persons” - trained by the manufacturer.

1. The staff training is carried our by the Vlastimil Mandik company that issues the “Certificate” on professional skills, the validity of which is 5 years and its prolongation is ensured by the “Qualified person” himself with his trainer.
2. After the “Certificate” is expired without prolongation, it becomes ineffective and it is deleted from trainer’s registration.

2. The installation of valves must be carried out in compliance with all effective safety work regulations and standards.

1. The attached duct must be conductively connected with the valve bushing in compliance with CSN 33 2000 - 4 - 41, - 4 - 47, -5 - 54, - 6 - 61.
2. To ensure reliable operation of the valve, it is essential to prevent the sealing contact areas of the valve saddle and disk from clogging by dust deposits, fibrous and other substances and solvents.

3. The serviceability testing must be performed at least every six months after putting the valves into service.

1. In the event that the valves are found incapable of fulfilling its function for any reason, this fact must be clearly marked on the plant. Before the plant is put into the state enabling to fulfill its function, the operator must secure the fire protection by another adequate way.
2. The results of regular checks, recognized shortcomings as well as all important facts relevant to functionality of the plant must be put down in the “Fire Prevention Book” and reported to the operator without further delay.

4. The thermal fuse replacement is carried out after the valve is removed from its bushing.
