ZECO gear operated butterfly valve is named after the way gear operated. ZECO pays attention to every detail of the valve. Every valve is inspected and installed strictly to ensure that the valve is in good condition and ready for operation. However, valve in the control of raw materials or the subsequent production and processing, inspectors only each link control well according to the requirements of technical engineer testing, pressure test, have answers to the very end to prove its performance. Moreover, even if the trial is successful, should check the valve stem seal and packing, and packing should be in the initial position. Valve is a special product with certain movement rule and friction rule.In order to achieve satisfactory performance, some parts of the machine should be carefully protected.At the right pressure, medium, temperature, the continuous service life of the valve will not be less than 6 years.
1. ZECO gear operated butterfly valve has light torque, which can be customized according to the requirements of users to open the quick opening type turbine butterfly valve with the number of turns twice smaller than the normal turbine butterfly valve, so as to manually open or close the valve for special emergency needs;
2. ZECO gear operated butterfly valve uses the laminated seal rings. It is designed by ZECO’s technical engineer to self align and make the valve sealing zero leakage according to the requirement of API 598;
3. ZECO gear operated butterfly valve can be designed in fire safe design, but it is not soft seated. ZECO can meet API 607 fire test requirements;
4. The stem of ZECO gear operated butterfly valve is designed in anti blow out. The anti blow out stem protects the operator from accidental pressurization of the line when maintenance is performed.
