Modular DBB valve

We provide high quality double block and bleed valve which are compact and has a light design, our valve has a lighter finish, easy operation as well as lower operating time. We have a standard specification which is made available and there are customized manufacturing standards, design choices, sizes, dimensions as well as material choices which can be by the customers.

This kind of valves is cost effective when compared to the traditional ones which combine the instrument and piping valves in a single unit. It is suitable for sampling systems, pressure instruments as well as pipes where spaces is restricted and drains for tanks, hydraulic systems.

Description

A double block and bleed is a single valve which has two seating surface that are in a close position and ensures the pressure is sealed from both ends of the valves by providing a cavity in between the seating surfaces.

Features:

  • Dimensionally accurate
  • High tensile strength
  • Long working life with smooth finish

Applications

The double bleed and block valve helps in saving space, cost, and likewise provide zero leakage capabilities from upstream to downstream. The valve likewise aids in the integrity check of seat seals. Apart from these functions, the double bleed and block valves can be used in a variety of markets and applications like LNG, petrochemicals, storage and transmission, marine and manifold valves in pipelines, natural gas industrial processes, products transmission lines which are refined.
Double block and bleed valves are utilized in areas where critical isolation is needed so as to ensure there is no leakage in the system. Based on the application and type of service, several types and options of double block and bleed valves are available to fit specific needs.
