CT-1
1. CT-1 offers the standard type electro-pneumatic positioner
and the air regulator as accessories and also offers several
options of positioner (E/P, Smart Positioner ) to be mounted
depending on request from end user.
2. Drive part is a compact and lightweight.
3. Spherical main valve offers great sealability and great
reduction of valve seat leakage (ANSI Class IV).
CT-1 is a pneumatic control valve. Its valve-opening is
accurately controlled by signals output from controller.
The single-seat globe valve body offers large capacity
and excellent controllability. The actuator is a multi-
spring, single-action type.
*1 Valve opens when the value of input signal increases.
· Available with ASME or EN flanged.
*2 Please apply air pressure between 0.4-1.0MPa for air regulator.
