► Description
2 inch size pneumatic actuated stainless steel material ball
1. Actuator type: Double acting, also have single acting
2. Ball valve size: DN50 thread connection Actuated ball valve
3. Connection: thread with BSPT, G and NPT
4. Fluid: Air, Water, steam, water treatment
5. Pressure class: 1000WOG
Actuator:
Full conformance to the specifications of: ISO5211, DIN3337, VDI/VDE3845, NAMUR.
The extruded high strength aluminum bodies are precision honed and hard anodized yielding an internal bore surface that can provide low coefficient of friction, smooth performance and a long service life.
All acting surfaces are fitted with high quality bearings, resulting in low friction, quite and high cycle life.
The two independent external travel stop adjustment bolts can easily and precisely adjust up to ±5º at both open and closed directions.
Multifunction position indicator with NAMUR standard is convenient for mounting accessories.
Pre-compressed load springs are convenient for safe mounting and disassemble operations.
Die-casted aluminum pistons and end caps are high strength and light weight.
Optional Viton and Silicone seals are available for low and high temperature
► Features
► Sizing spring return actuators
Example:
The max torque needed by the butterfly valve=104N.m
The torque after opened(operating)104X30%=32N.m
Air supply=5Bar
Air stroke 0°=134N.m>104N.m
Air stroke 90°=74N.m>32N.m
Spring stroke 90°=172N.m>32N.m
Spring stroke 0°=115N.m>104N.m
The above data show the actuator’s torque can satisfy the requirement of the butterfly valve.
