R295-3/4B — механический разъединитель, давление открытия 1,0 бар, DN20, Rp 3/4, Kvs 6

The mechanical separator R295-3/4B from Resideo (Honeywell) is designed to reliably protect drinking water systems from back pressure, backflow, and siphon from non-potable water. The device meets the requirements of the European approach to ensuring the hygienic safety of pipelines and operates in class GA according to EN 1717.

It is recommended to purchase Resideo (Honeywell) equipment for drinking water engineering systems from an official dealer - LLC Promelektronika (sales@prom-elec.com). This way, you get guaranteed delivery and professional support when selecting fittings for water supply.

It is also important: Resideo (Honeywell) equipment is still supplied in full volume to Russia.

Why choose R295-3/4B for water supply

The separator R295-3/4B is used in nodes where it is especially important to protect drinking circuits from contamination and negative flows when changing system operating modes. Its compact design and standardized connections help simplify installation and integration into existing pipelines.

• Stable operation at specified pressure modes: designed for an inlet pressure range of 2 to 10 bar.
• Low pressure drop: provides acceptable hydraulic characteristics and high throughput.
• Effective protection against backflow: reduces the risk of non-potable water entering the water supply network.
• Protection against siphon: helps counteract backflow during depressurization.
• Visual position indication: the spring cover has an indication of the closed state.
• Compliance with materials for water systems: the body and materials meet the requirements of KTW (approval of materials for contact with drinking water).
• Ease of installation: horizontal placement facilitates the assembly of the unit.

Technical compliance and materials

For the correct application of the separator, it is important to consider that it is made of red bronze RG5 and uses materials approved according to KTW. This is especially relevant when designing and operating facilities where confirmation of safe contact of materials with drinking water is required.

Where it is used

The device is used in engineering water supply systems where barrier protection requirements for drinking circuits are provided. The separator is suitable for scenarios where it is necessary to prevent the penetration of contaminated medium into the public water supply network.

How to make a purchase

To purchase R295-3/4B and other Resideo (Honeywell) equipment with correct selection for the project, it is recommended to contact the official dealer LLC Promelektronika — sales@prom-elec.com. This will help to receive current deliveries and reduce the risks of errors when selecting fittings.
