Embodiment Construction

[0014] Fluid control devices, such as rotary valves, are typically distributed throughout process control systems to control fluid flow rates of various fluids (eg, liquids, gases, etc.). Manually actuated valves are generally less expensive than automatically controlled valves (ie, control valves) and are often used where automatic controls are not available or required. In addition, standards such as those set by the Occupational Safety and Health Administration (OSHA) often require manual valves to remain locked when in use, for example, when handling hazardous liquids, to prevent accidental or Unauthorized operation.

[0015] In general, the exemplary manual valve actuators or controls described herein provide a lockout condition to prevent unauthorized or inadvertent actuation of the manual control (eg, in accordance with OSHA standards). The exemplary manual valve actuator or controller described herein provides a simplified configuration to reduce valve components, par...

Abstract

Manual valve operators having a locking device are described. An example manual operator includes a lever rotatably coupled to a locking plate and has a handle that pivots between a first position to prevent rotation of the lever relative to the locking plate and a second position to enable rotation of the lever relative to the locking plate. A lockout member is removably coupled to the handle. The handle has an aperture to receive at least a portion of the lockout member. The lockout member engages a portion of the lever to prevent the handle from pivoting between the first and second positions to prevent rotation of the lever relative to the locking plate when the lockout member is coupled to the handle.

Description

technical field [0001] The present disclosure relates generally to valves and, more particularly, to manual valve controls with locking devices. Background technique [0002] Fluid process systems typically use valves, such as rotary valves, to control the flow of process fluids. Rotary valves generally include a flow control element disposed on a fluid passage and rotatably coupled to a valve body of the rotary valve by a valve shaft. A portion of the valve shaft extending from the rotary valve is operatively coupled to an actuator (eg, a manual actuator or controller, etc.) that controls the flow control element. For example, a manual actuator or control has a rod or lever arm to couple the manual actuator or control to the valve shaft. The stem is rotatable between a first position and a second position to move a flow control element of the valve (eg, disc, ball, etc.) to a desired angular position to achieve a desired fluid flow through the rotary valve. [0003] Some...
