3/2 NC G1/4'' Brass 24VUC ATEX Solenoid Valve 0330 305982
Notice: This product is discontinued and replaced by 353596
Bürkert 3/2-way solenoid valve (type 0330) with G1/4'' threads and a 24V UC coil. Normally closed (voltage = open) and direct operating, so no differential pressure required. Suitable for slightly contaminated and aggressive media (media separation). For media with max 80°C at a differential pressure of 0-10 bar. Housing of brass with NBR sealing and a 3 mm orifice. The Kv-value is 0.18 m3/h (3 l/min at dp=1 bar water). Manual override feature. Certified up to ATEX zone 1.

Description
Bürkert direct operating 3/2-way solenoid valve with G1/4'' inner threads and 24V UC (alternating or direct current) coil. The valve has a brass housing with NBR sealing and an orifice size of 3 mm. The circuit function of the solenoid valve is normally closed, which means the valve opens when voltage is applied. Suitable for systems with a differential pressure of 0-10 bar and a maximum temperature of 80°C. The valve has a Kv-value of 0.18 m3/h, this translates to a flow rate of 3 l/min at the differential pressure of 1 bar (for water). This model is media separated and can therefore be used for slightly contaminated and aggressive media. The brass housing is durable, suitable for neutral fluids and resistant to many chemicals. The NBR (nitrile rubber) sealing is suited for water, air, alcohol and is fairly resistant to oil and petrol. NBR is unsatisfactory with oxidising fluids. Consult our chemical resistance chart to verify compatibility of housing and seals with the medium. Manual override feature can be used to commission the system. The valve is certified for ATEX Ex-Zone 1, so it can be used in potentially explosive environments requiring this certification. The valve has an IP65 rating if properly connected.
Important advantages
- ATEX certified up to Ex-Zone 1
- Can be used with slightly contaminated or aggressive media thanks to the media separated design
- As standard, it is equipped with a robust manual override for easy comissioning and in case of a power outage
- Good protection against the environment thanks to the IP65 rating
- Bürkert design: proven reliability & durability
0330 series
The Bürkert solenoid valve type 0330 is a direct-operated solenoid valve, meaning no pressure difference is needed to open the valve. This design is media separated, which allows for complete isolation of your fluid from the valve's working parts. This makes it a good solution for aggressive or slightly contaminated media. The valves can be delivered with DN 2 up to DN 5 or with a flange. The pressure range depends on the voltage, but has a maximum of 16 bar. The valve has a maintenance free pivot armature design instead of the common linear translating plunger. The valve is available in IP65 or IP67 protection. The valve has few moving parts, allowing for a long service life due to minimal wear on valve components. The 2/2-way and the 3/2-way versions are specifically designed for applications such as mixing, diversion and universal direction of media. The valves are available with different housing materials, such as brass, stainless steel, PP or PVDF in combination with different sealing materials. Finally, there are options for position feedback, bi-stable, vacuum variants, as well as ATEX explosion approved versions.
