CHARACTERISTICS OF VALVE

KAMAILONG all-welded ball valve has been designed
and manufactured in accordance with API 6D
standard and has been tested and inspected in 2.防静电设计：
accordance with API 6D/API 598 STANDARD. The
采用弹簧和小球静电引出装置，通过阀杆使球与阀体之间
fire resistance test of the valve complies with API 607
形成静电通道，从而使球体与密封圈开关过程中摩擦产生
and BS6755 standards. The valve has adopted the
built-in mounting plate structure. According to the 的静电通过阀体引到大地，防止静电火花可能引起的火灾
shape, the valve is divided into cylinder-shaped all- 或爆炸等危险。
welded ball valve and ball-shaped all-welded ball
valve. The valve seat has metallic sealing for primary 防静电装置
2.ANTI-STATIC DESIGN:
sealing and non-metallic sealing for secondary Anti-static Device
Use of spring and small-ball static electricity extractor, together
sealing; when nominal pressure is at CLASS600
with the electrostatic channel formed between the ball and the
(10.0MPa) or lower, the VITON-AED non-metallic valve body by the valve stem, the static electricity arising from
sealing secondary sealing will be adopted; when the friction between the ball and opening/closing of the sealing
ring is able to be taken to the ground by the valve body, which
nominal pressure is higher than CLASS600 (10.0 MPa),
effectively eliminates the fire or explosion risk that could possibly
DEVLON, PEEK, and all-metal sealing will be adopted. be caused by the electrostatic spark.
The main characteristics are as follows:
