Netherlocks TVL Protects Control Valves’ Calibrated Position
Houston, Texas (September 23, 2011) – Netherlocks’ TVL (Throttle Valve Lock) allows users to secure a throttle, choke or control valve in any position. The TVL is an ideal process control tool for ensuring that specific calibration settings are not changed without the proper clearance.
The TVL is integrated onto the valve and controlled by a single key which, when removed from the lockbox, renders the valve inoperable. Products like wires and chains to secure a valve allow small movements even while the lock is applied. When the TVL is used, it leaves no room for “play” and protects the valve’s calibrated position.
The TVL is constructed from corrosion resistant 316 stainless steel and designed to withstand extreme operating environments. It features maintenance-free operation and an integrated safety system to prevent unlocking without the designated key.
