Floating DBB Valve/Modular Integral DBB Valve

Floating DBB valve Modular Integral Double Block & Bleed Valves/Modular Integral DBB valve

The floating DBB ball valve body is generally is manufactured from forged or bar stock material to ensure a high integrity pressure envelope for the valve body, also called modular ball valve. Modular double block and bleed valve combines two in-line isolation valves into a single body with an additional bleed valve, so the integral compact body so called modular integral DBB Valve. The bleed valve used to drain or vent trapped fluid between the two closures to ensure highest level of safety in double isolation and bleed service.

Features:

● Modular compact valve design good body strength and long life
● Save space and weight
● Safety double isolation and bleed
● Reduced potential leakage path by all in one integral modular valve
● Bubble tight shut off
● Valve body design can be one pc body, two pcs body, three pcs body
● Valve end construction can be RF-RF, RF-SW, RF-NPT, NPT-NPT, etc.
● Material Stainless steel/Carbon steel /Duplex / Super Duplex/ Monel/ Hastelloy/ Inconel
● Application for critical chemical injection and process sampling,insulation of pressure indications or gauges, fields like cryogenic low temperature service corrosive fluids,high pressure

Valves can be produced by customer required data sheet and service, contact sales engineer for more details.

Floating modular DBB ball valve typical applications include manifold isolation, instrumentation or process equipment isolation.

Double Block and Bleed ball Valves (DBB ball valve) are used in the process industries to provide double isolation for additional safety such that the upstream fluid does not reach the downstream plant equipment. The bleed and vent valves ensure that fluid is drained from the cavity between the seals and to drain any fluid downstream of the process stream,minimizing any hazardous risk when transferring liquids or gas .
