  The factory setting allows the open torque switch to be by-passed for 5-10% of travel. This allows full boost power to open valve.

Factory sizing is done to design conditions or available operating conditions. Velan factory does not manipulate actuator manufacturer's settings. If valve is seeing much lower pressure differential, then close torque switch setting can be reduced. Please contact Velan Field Engineering Services for more information.
