进口二阀组原理特点

进口二阀组是与压力变送器或压力表配套使用。其作用是将差压变送器正、负压室与引压点导通或切断,或将正、负压室切断或导通。一般用于现场控制仪表上,为仪表提供多通路,减少安装工作量,提高系统可靠性。
The ‘G12FF’ Type 2 valve manifold is designed for remote mounting to static pressure transmitters. The separate vent valve gives full control of venting of the instrument, plus the ability to calibrate in-situ. Each needle valve head is designed for safe and reliable isolation,giving bubble tight shut off, with non-rotating & anti-galling tip and dynamic self-adjusting spindle seal to give long service life in a variety of service conditions.
