Spence Engineering Co. Inc.: SELF-CONTAINED REGULATOR
November 24, 2002
The EM33D self-contained regulator has a remote on-off control for batch process loops and automated building controls. According to the manufacturer, this regulator provides faster, smoother, more reliable operation than the control valves used in these applications. The company claims that using this regulator in place of a control valve eliminates the need for support systems and air input, as well as minimizing leaks and reducing the initial cost. The regulator is available in 3/8- through 12-inch sizes in cast iron and cast steel. The units feature packless construction, hardened stainless steel trim, and few moving parts for minimum maintenance and long service life, the company states.
