C210 Series
General
The type C210S Pneumatic Control Valve consists of a single seated globe valve and a pneumatic actuator, specifically designed for natural gas applications. The C210 provides smooth quiet operation, tight shut-off and long life. The specially designed valve seat is protected from possible erosion caused by flow contaminants. The C210S can be supplied with every brand of actuator or positioner available on the market.
Operation
The process medium flows through the valve in the direction indicated by the arrow. The position of the plug (32) is adjusted by changing the signal pressure acting on the diaphragm of the actuator (67). The valve stem (2) together with the plugs is connected to the actuator stem (67.1) via the stem connector (67.2) and is sealed with O-ring sealings (13)
Features
- Special patented valve seat
- Long maintenance intervals due to erosion-free enclosure of the seat ring
- Bubble-tight even at low temperatures
- Excellent control characteristics
- High degree of control accuracy
- Low lock-up pressure
- Fast response
- Actuators and positioners can be chosen as per client specifications
- Optimal noise reduction
- Using patented techniques and a noise reducing cage, the BAAI C210(S) can reduce noise production to an acceptable minimum.
- Noise reduction up to 40 dB(A) is possible, depending on the user's environment
- Low maintenance costs because of:
- Minimal friction
- Economic materials used
- Minimal number of standard parts
- Easy to assemble / disassemble because of:
- Regulator body remains in line during maintenance (top entry)
- Seat ring is easy to inspect
- High specific flow rate
- Hydrodynamically favourable design of regulator body
- Clear and complete technical documentation
- Satisfies up-to-date requirements
- Available in different languages
