LK quick closing valve systems were introduced in 2006. The now tried and tested quick closing valves and control stations are selected by ship yards worldwide and used on all types of vessels, rigs and platforms.

LK Valves & Controls have had great success in supplying LK quick closing control systems on many new vessels built in UK ship yards. Some recent examples are as follows:

  • An LK hydraulic control station plus 17 LK quick closing globe valves per ship, were installed on board all four Samuel Beckett Class ocean patrol vessels. All four vessels were built in a shipyard in Devon. The forth vessel in class, the LE George Bernard Shaw, was delivered to Haulbowline Naval Base in October 2018.
  • LK Valves & Controls delivered a hydraulic control cabinet together with a couple of bulkhead mounted hydraulic release units and a small number of LK quick closing globe valves to a UK ship yard in October 2018, all within 3 weeks of receiving the order. This LK quick closing valve system was for a new ferry named Red Kestrel launched in February 2019 and due to be completed in the spring.
  • LK Valves & Controls supplied 2 pneumatic control stations to the new polar research vessel the RRS Sir David Attenborough currently under construction in a UK yard. These port side and starboard side pneumatic control stations will be piped to all the quick closing valves aboard this vessel.

Quick closing valves are installed on tanks containing inflammable liquids as required by SOLAS. The control stations are installed in a safe area and, in an emergency, will rapidly and remotely close the valves that are mounted on the pipes from the vessels fuel or oil tanks.

Each LK quick closing valve incorporates a universal release cylinder which is designed to be used for hydraulic, pneumatic or mechanical release and is also fitted with an integral automatic fire release. The valves are a high quality compact design, available in straight and angled pattern and are Type Approved by all major Classification Societies.

The pneumatic control stations are available with a large number of combinations. These cabinets are equipped with one or more internal air vessels to guarantee the number of releases required by the major Classification Societies, even if the external air supply is lost during an emergency situation.

The hydraulic control stations are based on one handle for releasing one to six valves, the standard cabinet can hold up to six handles. Each handle has a separated oil reservoir and the system is a closed circuit independent from any external power. The hydraulic control stations are also available without a cabinet, delivered in groups of 1, 2 or 3 handles. Cabinets are available in painted mild steel or stainless steel with breakable glass window and hammer.

As an option both pneumatic and hydraulic control stations can be fitted with a 115-230V AC valve monitoring system (VMS) which can be mounted inside the control station cabinets or externally in a separate cabinet.    The VMS has a built-in un-interruptible power supply and a system monitor configured with alarm signals for low air pressure and loss of electric power. The unit incorporates 10 valve monitor modules, each module indicating open and closed position for up to 8 valves groups, in total 80 valves.
