三阀组是由三个互相沟通的三个阀组成。根据每个阀在系统中所起的作用可分为：左边为高压阀，右边为低压阀，中间为平衡阀。三阀组与差变送器配套使用,作用是将正、负压测量室与引压点导通或断开；或将正负压测量室断开或导通。
The ‘Y33’ and ‘YV33’ Type 3 valve manifolds are designed for remote mounting to differential pressure transmitters, with separate isolation for LP and HP inlets plus equalising valve for simple calibration. 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.
