The 210 series is a lock-up type regulator and complies with codes using this specification. The 210 series has been designed for maximum control function in an easy to use package. The series is intended for use with gas-fired boilers, steam generators, industrial furnaces, ovens, and similar high demand equipment. These regulators are suitable for natural, manufactured, mixed gases, liquified petroleum gases and LP gas-air mixtures. Because of balanced valve construction, Z models offer superior performance at an economic price to any other type atmospheric regulators.
