To open and close the sample valve and grab a sample, our standard sample valves are fitted with a proprietary spring-to-close hand wheel also known as the "Magic Hand Wheel". We offer two other spring-to-close options: spring-to-close hand lever and pneumatic actuator.
Depending upon your insulation requirements, one or two "cooling fins extension" can be fitted between the valve body and the actuator.
