Tools
In addition to the standard tool, special tools are required to assemble and remove some
parts (see Table 15-3). Use adjustable torque wrenches with a stop signal or that indicate the
torque being applied to achieve the right tightening torques. Valves in large valve sizes often
require tightening torques that can only be achieved through additional torque multiplication
by using a torque multiplier or hydraulic power tool. The required special tools can be pur-
chased from SAMSON.
