PN16 DN15-DN300 bellows sealed shutoff valve, maintenance-free, designed with external stem and guide rail, thus avoiding atmospheric emissions compared to conventional valves.

Work with:

• ferry,
• hot and superheated water
• thermal oil,
• technical water,
• gases,
• glycol,
• compressed air,
• neutral liquids, etc.

The PN16 DN15-DN300 bellows sealed shutoff valve is used in:

• processing industry,
• shipbuilding,
• air conditioning systems,
• installations and systems with thermal oil,
• in vacuum installations ... etc.

Complies with the pressure equipment directive 2014/68/EU.

Characteristics:

– Design and manufacture in accordance with EN 13709.

— Flange spacings in accordance with EN 558 series 1 and ASME B16.10.

— Flanges conforming to EN 1092-1, EN 1092-2 and ASME B16.5.

- Designed to be environmentally friendly.

- Materials carefully selected for wear, temperature and corrosion resistance.

— The valve does not contain silicones and asbestos.

- Simple design.

- Easy installation with the ability to install in any position from 270º to 90º.

- Internal design designed to provide the most favorable flow profile.

— Long life cycle with high work efficiency.

- Requires virtually no maintenance.

- Spindle with open indicator, locking mechanism, torque limiter and grease nipple.

- Male threaded spindle for higher operating temperatures and longer life.

- Protective seals with high quality graphite rings. They guarantee complete prevention of emissions to the atmosphere in the unlikely event of a bellows failure. This is a requirement of the DIN 4754 standard for heat transfer fluids.

- Removable gasket designed to prevent transmission of vibration to the valve stem.

- Double-walled bellows, strong, welded to the spindle, form a sealed assembly next to the seal and disc, without any possibility of rotation, to avoid breakage. The bellows disc is concave and connected to the bellows. This saves energy and helps keep the area around the valve handle at an acceptable temperature for operator safety.

— Stainless steel bellows are plasma welded. Helium-tested tightness ensures absolute reliability and long service life.

- Reinforced guide in the form of a bridge, providing thermal insulation.

— Ergonomic handle with a protective cap for the spindle.

— In accordance with safety requirements, the valve is an integral part of the kit. When attaching the valve at any opening or closing point, external locking systems must be used and the handwheel must never be dismantled.

— Machined closing surfaces that are ground, lapped and polished to achieve a degree of tightness that even exceeds the requirements of EN 12266-1 class A.

— All valves are carefully tested and checked.

— All components are numbered, registered and tested. Upon prior request, certificates for material, castings, testing and performance will be attached to the valve and to the instructions for use in accordance with PED 2014/68/EC.

IMPORTANT:

We recommend, if necessary, using heat-insulating and sound-insulating textile casings.

Optionally it is possible to order:

— Production from other materials for special working conditions (high temperatures, special liquids, etc.).

— Other types of connection.

— Seal with control cone.

- Soft seals.
