Solenoid valves designed for harsh and explosive environments

The release of new stainless steel solenoid valves has been announced by the Fluid Control Division Europe of Parker Hannifin. The 221G range offers unrivalled resistance to corrosion and aggressive chemicals, and with its ATEX certification, is suited to use in explosive environments.

With a durable high-grade 316L stainless steel construction plus fluoroelastomer (FKM) sealing to provide fluid and chemical resistance, the 221G series combines long life and reduced maintenance requirements in the harshest operating environments. Typical applications include those found in oil & gas, petrochemical, food processing and pharmaceutical installations.

The new valves provide an opportunity to reduce the overall size of customer installations and cut costs by up to approximately 10%, due to their high flow rates of up to 170ltr/min. 221G series valves are based on proven technology that has evolved over 40 years and is used in a popular sister family offered in brass.

A modular design of the valves allows assembly to a large range of coils including many with ATEX, IP67, UL/VDE approvals. This makes them ideal for use in applications where cleaning agents are present such as in car wash installations, industrial washing machines or food processing. The 221G series in stainless steel is available in a two-way, normally closed format with port sizes ranging from 3-8” to 1”.

Valéry Blanchet, Marketing Product Manager for Parker's Fluid Control Division Europe said: “This new stainless steel version makes the 221G Series exceptionally durable for applications where aggressive cleaning agents are present, and particularly for rigorous ‘wash-down’ environments.” She added: “They also provide a long-life and reliable solution in ATEX environments.”
