APV SV / SVS Butterfly Valves
Butterfly valves for process lines. They have two states: open — allows flow, and closed — blocks the flow in the line. It is switched by 90° disc turning, manually or remotely using a pneumatic actuator.
Brief specifications
- Type: rotary shutter with manual control, with pneumatic actuator
- Types: shut-off (overlapping), regulating the flow
- Disc and housing: 316L stainless steel with sanitary finish
- Internal polishing: ≤32 Ra (≤0.8µ) and others
- Connections: for welding, for thread, for clamp
- Dimensions: ISO 1” - 6” external. Ø pipes, DIN DN25-250
The lineup: Delta SV1, Delta SVS1

EP Positioning device
- The 8692 type positioning device is supplied by a well—known company in the industry - Burkert Fluid Controls.
- Used for pressure or flow control.
- There are no hidden costs, as with electropneumatic converters.
- The 4-20mA signal is connected directly to the installation without additional settings.
- Easy setup due to the automatic calibration function.
- LCD display for on-site valve installation and control.
Key advantages of APV SV / SVS
- Shaft bearings on top and bottom increase operational reliability and extend seal life.
- Profiled seals allow the valve to open despite vacuum.
- ATEX certification for hazardous media.
- Metal stop prevents overtightening of the flanges and mechanical overstressing of the seal.
- Easy identification of seals with APV/ part numbers.
- Visual indication of open and closed position.
- Unification and reliability - pneumatic actuator with constant torque value for sizes DN25-100/1''- 4''
