ST-550 AIR 2/2-way pneumatic high-pressure valve 350 bar

ST-550 AIR 2/2-way pneumatic high-pressure valve 350 bar

ST-550 AIR is a robust and reliable pneumatically controlled 2/2-way high-pressure valve, developed for demanding industrial applications where high demands are placed on safety, reliability and flow capacity.
The valve is used for quick and precise opening and closing of water flow in high-pressure systems.
The valve is controlled with compressed air, which means that there are no electrical components in contact with the water.
This makes it particularly suitable for wet environments, high-pressure cleaners, washing plants and industrial cleaning systems, where operational reliability and long service life are essential.
The complete design with butterfly piston, PTFE seals and stainless steel piston ensures low friction, fast response and minimal wear even at high working pressure and high water flow.
The solid brass valve body provides extra strength and stability in daily operation.
The ST-550 AIR is the obvious choice when you want a professional on/off valve that can handle high pressure (up to 350 bar), large water volumes and continuous industrial use.
