Pneumatic flange ball valve JB/T74~90, GB9112~9131, HGJ44~76

Pneumatic flange ball valve

Pneumatic ball valve switches easily and swiftly which meets the requirements of easy openness and closure of pipeline. The fluid has little resistance, durable, widely applicable, easy to install. Ball valves are light with small size and compact structure.

Pneumatic ball valves have pneumatic flange ball valve, pneumatic V-ball valve, pneumatic fixed ball valve, Flange V-adjusting ball valve, pneumatic sanitary ball valve, pneumatic 2-type ball valve, pneumatic 3-type ball valve, pneumatic thin ball valve, high-performance ball valve, pneumatic cut-off ball valve.

Feature:
1. It has little fluid resistance and has the least resistance of the valves even with the shortened diameter.
2. Stem thrust bearing reduces friction of torque caused by the stem, and smoothes the long-term flexible operation of the stem.
3. The seat has a good sealing, adopting PTFE and other elastic material to form the seal ring, which is easy to seal. The sealing ability of the ball valve incrases with the pressure of the media.

Standard:
1. Design: GB12237-89, API608, API 6D, JPI 7S-48.
2. Flange Size: JB/T74~90, GB9112~9131, HGJ44~76.
3. Structure Length: GB12221~89, ANSI B16.10, JIS B2002.
4. Examination: JB/T 9092, API 598.

Product specifications:
Caliber: DN15-400
Nominal pressure: PN1.6, 6AMPa
Flange Type: Flange Connection, JB79-59

Direction for use:

Temperature and pressure limitations
L Name shows the maximum and minimum operating temperature of the maximum allowable operating pressure.
L With the RTFE or PTFE material of the valve seat and sealing, the working temperature should limit between-290C to 2000C. Other types of operating temperature of valve seats and sealing, the plant should be subject to the examination of KI.
L Nominal pressure of the valve may indicate the maximum working pressure in the normal temperature condition. ( For example: PN4.0, indicating its operating temperature is -290C ~ 380C when the maximum working pressure is 40 Bar (4.0MPa).
L As for the use of electric or pneumatic actuator, please refer to the note of the statement.
