 Valve plate 
 High-performance PTFE valve plate can reach the minimum package thickness 3mm, PTFE material can be coated in the following products: 
 Path DN40mm ~ DN200mm valve, usually Teflon-coated stainless steel. Path DN250mm ~ DN600mm valve, usually high-strength 17-4PH stainless steel surface coated with Teflon non-CF8M 
 Stainless steel valve plate can be used on all valve sizes, valve plate design with high flow performance. One DN40-DN300 valve, the valve plate and stem the overall casting, with a strong rigidity, better turn the valve to reduce the gap, all of the valve plate has a full range of quality assurance that
