SS Butterfly Valve With Pneumatic Actuator , 1.5 Inch Butterfly Valve For Petroleum
Nyhau Fluid Equipment Co.,Ltd Butterfly valves have been a key system component in the hygiene industry for decades. They were developed, designed and manufactured for installation in pipelines for shutting off a flow of liquid. Suitable flow media include water, steam, petroleum, food, liquids in the chemical and pharmaceutical industry and pasty media.
The semi-finished products we use are sourced from stainless steel forges and have material certificates. The butterfly valves are subject to a continuous quality control process, which allows us to guarantee constant and consistently high quality. If you have questions on our product range, our team will be happy to provide you with help and advice.
Our butterfly valves represent maximum quality, reliability and hygiene. The butterfly valves are supplemented with a comprehensive range of accessories, and therefore offer the ideal solution for every application. In addition to a range of manual operations, the valves can easily be equipped with pneumatic or electric drives. A wide range of initiators and control heads are available to monitor performance. A clear advantage of our butterfly valves are the bearing bushes which minimise the wear on the axle, making our valves very durable. Of course, we also provide you with all standard approvals and test certificates for the materials used.
Typical Applications:
Hygienic Butterfly Valves are universal valves for isolation and control, in the food, dairy, brewing, pharmaceutical and beverage industries. These butterfly valves are designed to be easily automated with the SS Actuator, combined with the Easymind Electronic Control Top. Other automation options can also be made with other Pentair rack and pinion actuators upon special request.
