ZTVK's pneumatic actuated wafer butterfly valve combines progressed robotization with solid stream control for mechanical applications. Our valve highlights a one-piece design that diminishes working torque by 30% and amplifies benefit life to over 50,000 cycles. With sizes extending from 1"-40" (DN25-DN1000mm) and working weights up to PN16, this pneumatic butterfly valve conveys exact control for water, gas, and oil applications. The wafer plan guarantees compact establishment whereas keeping up prevalent fixing execution in temperatures from 0℃ to 80℃.
Our butterfly valves utilize a "twofold unconventional + diagonal seal" plan that essentially makes strides execution. This inventive approach diminishes the torque required for operation by 30% compared to standard plans. The result is smoother operation and amplified valve life.
The wafer-style body plan gives space-saving establishment between spines. You get solid fixing without the bulk of conventional flanged valves. This compact plan makes it idealize for tight spaces and retrofit applications.
The pneumatic actuator framework offers both single-acting and double-acting setups. Single-acting actuators incorporate spring return usefulness for fail-safe operation. When discuss weight is misplaced, the valve naturally returns to its foreordained secure position.
Double-acting actuators give exact situating control all through the 0° to 90° turn run. This gives you exact stream control for handle applications requiring particular stream rates.
We offer multiple material combinations to match your specific application requirements:
Body Materials: Cast iron, ductile iron, aluminum, stainless steel (CF8, CF8M, CF3M)
Disc Materials: Stainless steel (CF3M, CF3, CF8M), nylon-coated ductile iron, aluminum bronze, duplex steel (2507, 1.4529)
Seat Materials: NBR, EPDM, PTFE, VITON, FKM, Polyurethane
This variety ensures compatibility with different media and operating conditions. Stainless steel options provide excellent corrosion resistance for chemical applications.

This pneumatic actuated wafer butterfly valve exceeds expectations in petrochemical, control era, and water treatment offices. The fast 90-degree operation gives fast shut-off capability for crisis situations.
The pneumatic activation permits integration with plant mechanization frameworks. You can control numerous valves from a central area, progressing operational productivity and safety.
Beyond basic on/off control, our pneumatic butterfly valves offer exact stream direction. The circle position can be controlled to any point inside the 0° to 90° extend, giving you variable stream control.
This makes the valve appropriate for applications requiring stream balance or maybe than fair separation. Prepare businesses advantage from this adaptability in keeping up ideal framework conditions.
The vigorous development guarantees long-term unwavering quality with negligible upkeep necessities. The disentangled plan has less moving parts compared to other valve sorts, decreasing potential disappointment points.
Our 18-month guarantee covers fabricating abandons, and we give comprehensive specialized back counting establishment direction recordings and investigating manuals.
