High pressure DBB DIB structure Flanged End 3PC body Trunnion Ball Valve With Gear Operation

 

Main Features

 

Fire-Safe Test approved

Double Block & Bleed valves are designed in accordance with API 607

 

Double body gasket

All Double Block & Bleed valves are equipped with two body gasket. The first body gasket is in soft material and the second in graphite (if not otherwise required), this combination assures the best seal characteristic in whatever corrosive service as well as giving a fire safe design.

 

Anti-static device

In order to prevent static electricity which may light the fluid, static-conduction spring is set between the stem and the ball.

 

Anti blow-out proof stem

The stem is designed with integral T-Type shoulder to provide blow-out proof effectively. The design assures that the stem can not be blown out of the valve in the case of the packing being removed while the valve is under pressure.

 

Solid ball

The solid ball used provides straight through flow and real full-port performance characteristics. Hollow ball or cored cavity ball are not used.

 

Long life span

Special consideration was devoted to the attainment of enhanced life and operation of our valve throughout design, development, testing and manufacturing stages.

Valve designs combined with the selection of advanced materials are such that long periods of inactivity should not affect the operations of efficiency.

 

Low torque operation

Seat designs, stem-bearing system and stem seal arrangements ensure consistent minimal torque values.

 

Flow capacity

Valve design allows for high flow capacity in liquid or gas services regardless of whether the media is clean or dirty. Full port valves allow for pigging and ensure maximum flow capacity.

 

On site repairable

Simple user friendly design allows for quick and easy part replacement requiring minimal "Down Time".

 

DBB & DIB-1/ DIB-2

 

Double Block and Bleed (DBB) API 6D DBB-1 -- The spring loaded seats are always in contact with the ball to provide an effective seal even at low differential pressures. When the pressure is simultaneously applied to both sides of the ball in the fully closed position, the body cavity is isolated from both upstream and downstream sides, allowing Double Block and Bleed operation.

 

 

Double Piston Effect (DPE)

API 6D DIB-1 -- Double Piston Effect seated ball valves are available upon request. With DPE configuration, the downstream seat will still keep the valve fully sealed, in case of failure of upstream seat. Body cavity over-pressurization can be released through a relief valve on the body. API 6D

DIB-2 -- A combination of double sealing features on the downstream side and single sealing on the upstream seat is recommended. This configuration maintains the sealing capability of the valve in case of failure of the upstream seat and release of the body cavity overpressurization through the upstream seat.
