ZTVK's air operated butterfly valve combines progressed pneumatic innovation with strong designing for predominant stream control execution. Our valves highlight a one-piece design that decreases opening torque by 30% and amplifies operational life to over 50,000 cycles. With sizes extending from 1.5" to 48" (DN40-DN1200mm) and weight evaluations up to PN16, these industrial-grade valves provide solid robotization for your basic applications. Each valve experiences thorough testing and comes with an 18-month guarantee for peace of mind.
When you require solid stream control robotization, our butterfly valves with pneumatic actuators offer the idealize arrangement. You get quick reaction times, exact control, and negligible support requirements.
Our valves utilize compressed discuss as the control source to drive the actuator. This turns the valve stem, turning the plate 0° to 90° for speedy opening, closing, or stream control. You can select between single-acting or double-acting actuators based on your security requirements.
Advanced Design Engineering
Flexible Material Options
You can select from different body materials counting pliable press, CF8/CF8M stainless steel, and WCB cast steel. The plate alternatives incorporate pliable press, stainless steel grades, and aluminum bronze for erosion resistance.
Reliable Pneumatic Operation
The actuator body highlights expelled aluminum with difficult anodizing for solidness. Single-acting models incorporate spring return for fail-safe operation, whereas double-acting adaptations give greatest control flexibility.
