ZEA BIO type valves


Project Description

Zawór elektromagnetyczny ZEA BIO

  •     2/2 NC cl.A
    • Fluids: gas fuels (natural gas, propane-butane, biogas), air and other non-aggressive gases
    • the details of this valve, which are in direct contact with the medium fluid, are made of materials resistant to the corrosive effect of biogas
    • direct acting
    • poppet
    • manual regulation of flow (option)
    • suited to zero pressure differential conditions (ΔPMIN= 0 bar)
    • permanent strainer built-in
    • conforms to PN-EN161

• designed for reliable service in all types of installations and appliances (e.g burners, heating boilers), supplied from low pressure gas network
– biogas from wastewater treatment plants
– biogas of landfill origin
– biogas from installations for processing animal or plant waste
• coke oven gas for feeding cogeneration systems, sewage treatment plants and rubbish dumps
• as a part of the gas train supplying gas appliances (mentioned above), the valve will act as an automatic safety shut-off valve acc. to requirements of p, PN-EN 746-2 standard

* – maximum width of valve

• the operation of these valves does not depend on the process pressure of the medium fluid nor the flow rate
• they can operate independently of the existing pressure difference ΔP on the valve
• suited to zero pressure differential conditions (ΔP min= 0 bar)
• their design limitation is the value of the maximum pressure difference ΔPMAX that can occur on the valve. It depends on the lifting force of the electromagnet and the nominal diameter of the valve flow orifice (the larger the nominal diameter, the smaller the ΔPMAX value for the same electromagnet)
• with a pressure greater than the maximum differential pressure ΔPMAX, the valve will not work properly (it will suspend)
• short actuation time (from a dozen to several dozen ms)
• high reliability due to the simplicity of the design and a small number of internal parts
• long lifespan – some designs can reach up to several million work cycles
