  If your manually controlled, gas-powered Emerson Industrial Equipment is experiencing a slow, jerky, or partial stroke, consider the following: * Check and increase the supply pressure. * Ensure the shutoff/speed control is open a few turns. * Blow out the lines to address a dirty gas filter element. * Disconnect the operator from the valve if the fluid is contaminated. If these steps do not resolve the issue, the operator and valve stops might not be in the same position.
