00221934 00221936 00221935 Burkert Germany 6281 Type 221936 Diaphragm Solenoid Valve G3/4

Product Description:

This valve utilizes a servo-assisted mechanism featuring a pilot isolation diaphragm combined with plunger actuation. The pilot valve operates as a rotary armature or rocker solenoid valve equipped with an isolation diaphragm, ensuring that the medium does not pass through the pilot orifice. This design offers excellent resistance to clogging.

When opening, a minimum differential pressure of 0.2 bar is necessary to actuate the main diaphragm. The pilot valve manages the pressure within the main chamber to facilitate valve opening. During closing, a damped design provides a quiet, water-hammer-free shutdown, which effectively reduces pipeline stress and noise pollution.

Additionally, the valve supports energy-saving features through an optional KD dual-coil technology. This system automatically decreases power consumption during steady-state operation after the initial actuation, making it particularly suitable for long-term continuous use.

The valve offers a wide range of material compatibility. Its body can be made from either brass or stainless steel, and it supports sealing materials such as NBR, EPDM, and FKM. This versatility allows it to be used with water, various gases, general chemicals, and in high-temperature environments.

Reliability and durability are enhanced via a centrally threaded coil that is vibration-resistant and encapsulated in epoxy resin to withstand chemical exposure. Furthermore, the pilot isolation diaphragm design minimizes the chances of clogging and leakage.

The valve also provides flexible customization options, including an optional manual override for maintenance and commissioning, KD energy-saving coils, and explosion-proof certification. These features enable the valve to perform effectively in harsh and hazardous environments.

Compliance with multiple standards is ensured, including drinking water regulations, ATEX explosion-proof certifications, and UL/CSA standards. This comprehensive compliance makes the valve suitable for use across different regions with strict regulatory requirements.

This valve is commonly utilized in municipal and industrial water treatment systems as well as drinking water supply networks. Brass models designed to meet the relevant regulations are typically applied in these scenarios.

In the food and beverage industry along with pharmaceutical liquid preparation systems, stainless steel valves combined with EPDM or FKM seals are chosen to satisfy hygiene standards.

The valve also supports transfer systems for compressed air, hydraulic oil, and various general chemicals, with material selection tailored to the specific properties of the medium.

For fluid control in hazardous areas, models certified to ATEX and IECEx standards are available to ensure safe operation.

When selecting this valve, it is essential to ensure the actual operating differential pressure is at least 0.2 bar. Insufficient differential pressure will prevent the valve from opening reliably.

Choosing medium compatibility is critical: a stainless steel body with FKM seals is recommended for strongly corrosive media, while standard brass bodies with EPDM seals are suitable for drinking water applications.

To optimize working conditions, opting for the KD dual-coil version is advantageous for continuous operation by reducing energy consumption. Explosion-proof certified models should be specified for use within hazardous environments.

Proper installation and maintenance include fitting a strainer upstream to block impurities from entering the valve. It is also important to avoid imposing pipe stress on the valve body by independently supporting the pipeline. The manual override function is intended strictly for commissioning and emergency situations and should not be used for extended forced valve opening.
