When you require dependable stream control in mechanical applications, ZTVK's motor actuated butterfly valve conveys extraordinary execution with progressed designing. Our electric actuator-operated valves highlight a twofold unpredictable + diagonal seal plan that decreases opening torque by 30% whereas amplifying benefit life past 50,000 cycles. Accessible in sizes from 1.5" to 48" (DN40-DN1200mm) with working weights of PN10/PN16, these engine activated butterfly valve units give exact stream direction for water, gas, oil, and chemical applications at temperatures from 0℃ to 80℃.
Our valve joins auxiliary optimization that sets it separated from customary plans. The twofold unpredictable arrangement with angled fixing innovation altogether diminishes operational push whereas making strides fixing performance.
You'll appreciate the cleverly extension capabilities built into each valve. Saved interfacing suit electric and pneumatic actuators, permitting consistent overhauls to mechanized control frameworks without supplanting the valve body. This future-proof plan secures your speculation whereas empowering framework evolution.
ZTVK offers comprehensive fabric compatibility to meet your particular application prerequisites. Select from carbon steel WCB, stainless steel CF8/CF8M, or duplex steel alternatives. Our stainless steel butterfly valves give prevalent erosion resistance compared to conventional cast press alternatives.
The plate materials incorporate bendable press, CF8, CF8M, and aluminum bronze arrangements. Situate materials include EPDM, NBR, PTFE, and VITON alternatives to guarantee chemical compatibility with your handle media.
Electric incitation gives exact stream direction through 0-90° fractional turn development. The framework acknowledges 4-20mA or 0-10V control signals from mechanical mechanization frameworks, empowering precise valve situating for stream, temperature, and weight control.
Working control choices incorporate AC 220V and AC 380V arrangements for both exchanging and balancing applications. This adaptability guarantees compatibility with existing control foundation.
