Control Valves Data Sheet

This document provides specifications for control valves, including: 1. The valve will have a travel indicator and smart positioner taking a 4-20mA HART input signal to modulate the valve fully open to closed. 2. The valve body will be made of carbon steel or stainless steel, with a plug trim and double block and bleed 3-way port configuration. 3. The actuator will be a diaphragm type mounted vertically to modulate the valve in response to a 4-20mA input signal to the positioner.
