API Bottom Loading Coupler, size: 4 in accordance with API RP- 1004 is designed for effortless and leak-proof tight connection to the Tank Trucks mating API Adaptor. The unit provides dependable and low maintenance service.
The coupler contains 3 trigger mechanisms to prevent accidental opening of the valve and 5 interlock lugs for secure holding during loading operations. Hence, unless the coupler is tightly connected to an API adaptor, its valve cannot be opened and also, cannot be disconnected unless the valve is closed.
The unit has hard anodized aluminum body, sleeve and valve with a 4 TTMA mounting flange. Stainless steel internals with chrome plated handle. All seals are Viton and bushings are PTFE. Hydro tested at a pressure of 16 kg/cm (g) before dispatch.

Most popular and have several advantages. Small and compact unit requires little operating space. Operating principle is simple- lowering the arm winds the spring tighter and lifting the arm spring unwinds. We offer 3 different sizes of spring assemblies with progressive higher lifting capacities.

It comprises a long compression spring encased in a round shaped pipe that compresses the spring as the arm lowered. Adjusting screws are located outside the casing for adjustment of spring tension with a standard tool. 3 different sizes of spring assemblies are offered with progressive higher lifting capacities.

Vacuum breaker permits quick draining of the residual product from the arm after the loading operation is completed.

Materials of construction are aluminum, brass and stainless steel. Standard size is .

Ferro Tube offers spring type, small and compact model of vacuum breakers which are highly effective and provides dependable and long maintenance free performance.

Position Sensor and Overspill Protection Device can be incorporated with our all Top loading arms as per customers requirement.

Position sensor detects the position of loading arm and Overspill device detects the product level and prevent from overflow during filling operation. Both these devices are designed for rugged services, provides dependable and trouble free performance.

Main component of these devices is Sensor. Sensors are proximity type and transmits NAMUR signal. Each sensor is encased in their respective PTFE lined metallic Housing along with accessories for generating signal at a desired set point. Sensor Housings are mounted on the loading arms at their respective strategic locations.

The cables ends of each sensor are terminated at a Barrier/ Isolated Switch Amplifier rated 24V DC or 220V AC as per power supply at customers installations. Barrier is housed inside a flameproof (Ex-d, IIA/ IIB) and weatherproofs (IP 65) Junction box which mounted on a permanent Platform structure. However, the cabling beyond the junction box to batch controller falls under the scope of customers.
