Oval Handles (OH) are intended for several different applications, and can be installed where a standard lever handle might encounter interference from adjoining piping. Oval handles also prevent accidental valve operations, since they have less projection than a lever handle, and require more turning force to operate. The oval design prevents clothing or other material from being hooked onto the valve handle, inadvertently causing it to open or close. Because they are a safer option, OSHA requires the use of oval handles in many industrial applications.
Tee handles (TH) offer the same space savings as oval handles, with a slightly shorter end-to-end dimension. Tee handles require more handle force to operate, so accidental openings can be reduced. The increased torque may limit the availability of larger sizes, so please contact your customer service rep for help with sizing.
Locking devices offer the end-user the security of a lockable handle to prevent tampering. This added level of safety is required by OSHA in many applications. With the use of a standard 5/16" padlock, the locking handle (LD) can be locked in either the full open or full closed position. The handle and locking device are manufactured using stainless steel material (LL) for additional strength and corrosion resistance. Locking devices are also available on oval handles, and come as an extended locking handle (XLD). This robust design can be locked in the open or closed position with the use of a standard padlock.
