| S E Q U E N C E | SEQUENCE VALVE DIRECT ACTING, NORMALLY CLOSED, WITH EXTERNAL PILOT & INTERNAL DRAIN ■ Sealed pilot option available. ■ Hardened working parts for maximum durability. ■ External parts zinc plated. ■ Adjustable and tamperproof versions available. OPERATION The adjustable spring-loaded spool is shifted at valve setting by pilot pressure on port [3] allowing restricted flow from ports [1] to [2]. Further pressure on port [3] increasingly opens ports [1] to [2]. Ports [1] and [2] remain normally closed when port [3] pressure is below the valve setting. Back pressure on port [2] adds to the valve setting. |  | |||||||||||||
