The pneumatic valve, double disc butterfly check valve the main characteristics and application of 2)

pneumatic valve check pneumatic butterfly valve is the main characteristic of double disc:
double pneumatic butterfly valve pneumatic valve check pneumatic valve nominal pressure PN. MPa吗? 。 MPa, CLASSLb ? 磅; DN DNmm? Mm, NPS/'? ”; Working temperature - C ? C all sorts of media is used to prevent pipeline back. Part of the H series of pneumatic butterfly valve, double disc check valve pneumatic valve production, through the use of different material, suitable for water, steam, oil, nitric acid, strong oxidizing medium and urea, and other media. Pneumatic double disc check valve pneumatic butterfly valve main features are: a, wafer butterfly pneumatic valve check double pneumatic valve pneumatic valve structure length and structure only traditional pneumatic valve flange check / / short length; Weight, small volume, light weight, the only traditional pneumatic valve flange check/to /; Double pneumatic valve, pneumatic valve pneumatic butterfly valve, water hammer pressure is small; , the horizontal and vertical pipes can be used, easy installation; Pneumatic valve, butterfly double pneumatic valve flow is smooth, fluid resistance is small; , sensitive, sealed performance is good; , pneumatic valve pneumatic butterfly valve two-stroke pneumatic valve is short, small; , the overall structure is simple, compact, good appearance; , long life and high reliability. Pneumatic valve check pneumatic butterfly valve, double disc standards and specifications:, design and manufacturing: AP, APID, JB/T and structure length: API, APID, DIN, JB/T; The pressure - Temperature level: b. , DIN, GB/T, HG, HG, SH, JB/T, test and inspection: API, JB/T, pipe flanges: JB/T - ,GB / T - Standard: HG - 、SH ANSIB。 ，DIN - According to GB/T, API, ASMEB. 。 Pneumatic valve check pneumatic butterfly valve city construction, chemical industry, metallurgy, petroleum, pharmaceutical, food and beverage double disc, the scope of environmental protection
