Suitable Media & Application: Wafer and other neutral medium, working temperature from -20 to 120℃, the application of the valve can be municipal construction, wafer conservancy project, water treatment etc.
Pressure Testing: ZFA Valve strictly execute API598 standard, we do both side pressure testing for all the valve 100%, guarantee deliver 100% quality valves to our customers.
17 Years Manufacturing Experience: ZFA Valve focus on valves production for 17 years, with professional production team, we can help our customers to archive your goals with our stable quality.
Precision CNC Machining: We use CNC machining to process the valve disc, control the precision of the valve by ourselves, guarantee good sealing property from low to high temperature.
Tempered Stainless Steel Stem: Our valve stem is stainless steel material, the strength of the valve stem is better after tempering, reduce the transformation possibility of valve stem.
Rigorous Quality Control: The quality inspection from the blank to the finished product is 100% guaranteed.
Self-Lubricating Bushing: The sleeve bearing is self-lubricating type, so the friction of the stem is small so you can open and close the valve tightly.
18 Months Warranty: All our valves have 18 months quality warranty, if any leakage, you can contact us for the after-sales issue.
Compact Flange Design: The flange type butterfly valve is made by ductile iron, it has a great feature that short face to face dimension and easy to install. The valve torque is small and the sealing surface between the seat and disc is small.
Standard Versatility: Our valve can be produced by different kinds of materials, it’s produced by international standard and national standard according to your requirement.
Epoxy Coating Finish: The valve body and inner parts are produced by CNC machine to guarantee the precision of the valve production. It’s an epoxy coating body with good looking appearance.
