	Contact the sales office for torque figures not shown above.
	Torques shown are for full rating and are linear with pressure. Donot use less than the minimum sizing DP when calculating operating torques.
	DHC suggests a minimum of 20% Safety Factor on the above forques.
	Although the valves are suitable for Bi-Directional use, the offset geometry creates a Preferred direction of flow which if used(for uni-directional flow) an show a torque and actuator size reduction.
	Maximum shaft torque is for 17-4PH in the designed condition. For other shaft materials, consult DHC for guidance.
	Run torques are 40% of the Preterred direction Opening torque.
	Torques shown are valid for temperatures of -100℃(-148℉) to +538℃(+1000℉) For temperatures outside this range consult DHC.
	Torques shown assume a maximum liquid velocity(pipe line) of 5㎧. For higher liquid velocity, where hydrodynamic torque may need to be considered, consult DHC.
	Please ensure that any actuator chosen to operate the DHC valve is capable of supplying 5 overtravel and has mechanical limit stops controlling the closed position.
	Note that operators must be dowellde to the valve mounting plate. Dowels with be supplide with bare shaft valves but it is the purchasers responsibility to ensure separately purchased operators and mounting kits are machined to accommodate these dowels.
	If in doubt, contact the sales office.
