With mesh top alum. box to eachmanhole that not higher than the rollover damage protection system. 

Emergency (foot ) Valve

2 x 4” EMCO foot valve, one at middle of bottom tanktrailer, the second at the rear of bottom tank trailer, conforming to latestedition of API RP1004 requirements. 

Shall be mounted internally on a sump located along the tank centerlineat thebottom of the tank. The sump depth for mounting the emergencyvalve should be 100 mm (4-inches) deep.

Shall be pneumatic type, equipped with signal for OPEN / SHUT indication, and a mechanism to facilitatemanual opening of the valve in the event of accidental loss of airpressure.

Shall be installed in a manner that will allow for its removal from the underside of the tank.

Pneumatic Control System

The system shall be integrated with the vehicle braking system to providebrake interlock for drive away protection during loading/unloadingoperations.  

With pneumatic control block for the bottom valves.

Emergency Cut-off Switch

EMCO , 2 pcs 

Discharge Valve (Adapter)

2 x 4”  aluminum alloy API discharge valve withoperating handle, flow vision and sight glass flange locatedin the center of tanker’s right side (looking from rear trailer). 

Discharge Valve Coupling

Vapor Recovery System

With pneumatically operated high flow vaporvent valve, 4” vapor collection piping inside the tank connected to the 4”quick coupling type vapor adapter 

A drain plug shall be provided at the lowest point of the vapor adapter toallow for drainage by gravity of any accumulated product in the vaporline 

Vapor return piping system shall be designed to provide the lowestattainable pressure drop during operation. No rubber hoses shall beinstalled on the vapor ventpiping on the tank.

Vapor Adapter shall be located to the right (curb) side of the tank truck,in an area adjacent to and left of the bottom loading adapter(s). Thehorizontal distance between the vertical centerline of the Vapor Adapterand left most Bottom-LoadingAdapter shall be 350 mm. The verticaldistance (height) between the horizontal centerlines of the VaporAdapter and the Bottom Loading Adapter(s) shall not exceed 200mm.

Barrel Bottom Piping

4” aluminum alloy piping system for each compartment, designed to keepthe overall pressure drop as low as practicable under design flow condition.

Design working pressure for piping shall be 5 bar . Piping shall betested for a test pressure of 1.5 times the working pressure.

Piping originating from the emergency valve(s) and leading to the bottomloading adapter(s) shall have a downward slope with respect to horizontallongitudinal axis of the cargo tank to facilitate product flow.

Anti–Static System

With 3 meters length retractable wire reel for anti-static, located atdischarge valve control area 

Overfill Protection System

The design of the overfill prevention system shall conform to the requirements stipulated in the latest edition of API RP1004

With EMCO 5 wires optic overfill protection system, consisting of thefollowing:

A five -(5) wire system optic sensing probe in each compartment, mounted either directly in the accessory port of the manhole coverassembly or alternatively into a 50mm (2 in.) NPT fitting secured to thetank shell.Designed for a temperature range of -20°C (-4°F) to+60°C (+140 °F) and shall have fog resistantcharacteristics.

The response time from sensor going wet to the change ofstate of the signal at the interface six-pin receptacle shall not exceed 0.5seconds.

Level Reading Stick 

Nil

Antistatic Internal Cable

An Antistatic Internal Cable Conductor between top and bottom of tankshell shall be provided.The cable shall be made of stainless steel materialand installed between the Emergency Valve sump and the underside of theManhole Cover (in the vicinity of the overfill sensing probe) close to thecenter of tank shell.
