Home > Safety Device > Safety Valve [XSz (with a dynamic monitoring function)] 1.  Conformed to EN692 and EN954-1 Standards 2.  Interfacing can be done easily 3.  Poppet-Type piston assembly with polyurethane shield 4.  Cross-flow patent granted 5.  Soft brake/Soft clutch modules for large machines are usable 6.  Adjusted volume chambers and orifices The air pocket is the secret. The air kinetics from the piston action is released through the air pocket at 300ms. , where all the air pressure is released. Thus, it is possible to prevent unsafe activation of the device through adherence of dust and unbalanced electricity run through.
