M type plug connector There are no sliding parts in the valve (ex: spool, pistons, etc.), so the valve is able to function continuously and reliably at low pressure. The sealing function is performed by diaphragm. Therefore, the valve is non-lubricated for applications that are sensitive to lubrication.
