Application:
　　The CV115 was developed by Pumason to provide the most accurate control available
for fractional flow services; whether for pilot plant installations,test stands, R & D
facilities, or for specialized usage in processes such as dosing, injection and venting applications.The convenient-removal design ensures the valve is easy to clean or repair. The diaphragm can be easily accessed from the top allowing some repairs to be conducted without removing the valve from the line.
