Imported pneumatic bellows stop valve
(Germany Robert brand)
Product Description
Germany Robert imported pneumatic bellows stop valve adopts bellows sealing structure, and changes the seal to static seal. Performance is greatly improved. The bellows globe valve achieves double sealing. The stainless steel bellows protects the seal and the valve stem packing protects the seal. If the bellows fails, the valve stem packing will also prevent leakage. Ensure that the valve does not leak under conditions of high temperature, high pressure, and strong media penetration. The sealing surface can be overlayed with stainless steel or cobalt-based carbide or use various combinations of non-metallic materials to form a sealing combination with good wear resistance, corrosion resistance, anti-friction performance and long service life to meet the requirements of various working conditions. Ensure that the valve has neither external nor internal leakage.
