Netherlocks interlocks
Når du vælger Netherlocks interlocks, fjerner du risikoen for menneskelige fejl.
Med interlocks sikrer du, at kun den rigtige ventil kan åbnes eller lukkes – og altid i den korrekte rækkefølge.
Systemet guider dine operatører hele vejen, så det ikke er muligt at omgå det.
Ventilerne betjenes med en lineær nøgle, som fører operatøren gennem en fast proces med en på forhånd defineret rækkefølge – og med unikke nøgler til hvert trin.
Et produkt, der dækker alle dine proceskrav
NDL valve interlock
Du kan montere NDL ventilinterlock på alle kvartdrejningsventiler, f.eks. kugle-, butterfly- og plugventiler.
Interlocken frigiver først en nøgle til operatøren, når ventilen er helt i endeposition – enten helt åben eller helt lukket.
Operatørerne bliver guidet trin for trin gennem udvekslingen af interlock-nøgler.
Interlocken erstatter det originale ventilhåndtag med et nyt, rustfrit skydehåndtag.
MRL valve interlock
You can mount the MRL Valve Interlock to any type of multi turn, hand wheel or gear operated valve. The interlock will only release a key to your operators once the valve has reached its full stroke – fully open or fully closed. Your operators are guided by the release of coded interlock keys, which will only be accepted by the next valve interlock in the sequence. The interlock replaces the original valve hand wheel.
Closure lock
With the Closure Lock, you interlock the closure door of a pigging vessel, preventing it from opening. This is a critically important product – you must at all costs, prevent access to a pressurised vessel. When combining the Closure Lock in an interlocking sequence, you guarantee that the isolation valve and the vessel is vented and drained, before your operators can unlock and open the door.
Actuator locking system
The ALS (Actuator Locking System) is a mechanical interlocking device for your motor operated valves. It locks and regulates operation of the local controls and manual override of your actuators. With the ALS, you can fully integrate your actuators into valve interlock procedures and sequences.
Actuator switch lock panel
Using the Actuator Switch Lock Panel (ASLP) you can manage the local controls of your actuators from a remote location. You can lock and regulate the operation of components of an actuator, mechanically locking (blocking) the power switch (supply), the manual override function and the position indicator.
Electrical switch lock
With the Electrical Switch Lock you can control the operation of electrical switches. With an Electrical Switch Lock you integrate operation of electrical devices into your valve interlock operations. This helps you determine certain safe process conditions – for example, preventing startup of a pump until the suction valve is opened.
