The tagging on our products, keys and dust caps has a preliminary important purpose. To help operators in the field, during change over, to correctly identify the next step in their procedure or sequence. Furthermore, it shows relevant information on the lock, keys an the steps in the procedure. The key that is present in the control room tells the operators the status of any particular system.
Alcatraz Interlocks can supply the tagging on the key and dustcap in multiple colors. Up to 3 lines of 13 characters.
Alcatarz Interlocks can act as a consultant and advise on the correct operating procedures on almost all critical processes. Due to our extensive experience gained in over 20 years.
A valve interlock is a single- or dual-key assembly which locks the valve in two positions - open/closed - with one key trapped within the lock assembly and one key free.
The mounting kit connects the rotating part of the valve, spindle or stem, with the rotating part of the lock and or the bearing.
The kit connects to the static part of the valve, top flange or bonnet, with the static part of the interlock (body). Both parts are designed and manufactured to that particular valve.
The valve interlocks are manufactured after the design work is completed. The design works are based on the dimensions of the valve top works: yoke, stem, hand wheel connection, spindle, packing gland etc.
We manufacture our mounting kit (designed bracket) from AISI 316 stainless steel only.
To install an interlock, the existing handwheel or lever is removed from the valve. Then the mounting kit is bolted onto the valve. Our interlock is fitted on the mounting kit.
As a standard we replace the original handwheel or lever with our own handwheel or lever. This new product does not change the original characteristics of the valve. Our new lever is standard AISI 316 stainless steel, the hand wheels are Zinc coated cast iron.
If there is a desire to keep the original hand wheel or lever, Alcatraz is able to produce hand wheel and lever adapters allowing to refit the original handwheels and levers.
No welding or grinding is done to the valve nor are any infringments made to the pressure containing or presurre retaining part of the valve.
Of course we can. We have 4 standard types of valve interlocks: DML1, DML2, SBL, for handwheel operated valves (gate, globe, gear operated) and ball valves. And a DQL for lever operated valves.
The mounting kits are custom made to the top works of the valve. So Alcatraz can design a solution to fit on any type or size of valve.

The answer is no, we have eliminated grease. We use the special NCS-30 Artic Nonconductive Thread Compound carbon fibre. All our components are dry movement parts and only have a PTFE glaze.
Grease can only attract dirt and get dried out so this is a significant improvement compared to other locking suppliers.
In the last few years we have handled several projects with more than 14.000 valve interlocks used. In most cases we also provided the on site service, training and commissioning.
The Integral Multi Turn & Integral Lever lock types from Alcatraz Interlocks were thoroughly tested and Alcatraz was awarded with the Fire Test Certificate, in accordance with ANSI/API Standard 607, 6th edition, September 2010 standards. Customers can be assured that even in the event of a fire the interlocks will function safely as designed.
Alcatraz Interlocks are designed to withstand temperatures of 1000°C+.
