How to Change a Standard Model 121 to a V-Port
Sometimes different applications call for different configurations. With this video, we will show you how to change the standard Model 121 to a v-port. A v-port helps improve the rangeability for your regulator so that at low flows, you regulator is more stable and prevents your diaphragm from fluctuating. The v-port trim is also available for all our Model 441 and Model 461 regulators. Contact us if you have any questions about the v-port or to inquire about how to order.
