Vertex Works as a completely automatic valve that shuts off the pressure of the instrument when the system pressure exceeds the pre-set pressure.  We also set pressure adjustments made by manipulating an external adjusting screw and lock nut. Adjustable Overload Protector manufactured by Vertex is a 316 stainless steel valve designed to avoid damage to instruments and systems through overpressures. Generally the valve will be held open by an adjustable compression spring; and in the event that an overpressure exceeds the spring pressure, the valve closes. 

With experience of manufacturing needle valve and related accessories, Vertex guarantees to offer you the best products with reasonable price. If you are looking for quality Adjustable Overload Protector, please don’t hesitate to contact us.
