Scope & approach

Built around
the application

PIP supports industrial valve procurement in Oman and across the GCC, covering floating and trunnion-mounted ball valves, gate valves, globe valves, check valves and double block and bleed assemblies. Our supply scope includes forged and cast designs, material selection and actuated valve packages. Review the manufacturing range below for available sizes and pressure classes. For duties beyond a standard design, explore our project-specific special valves.

How we can support you

  • Ball valves: floating, trunnion mounted and top entry
  • Gate, globe and check valves
  • Double block and bleed assemblies
  • Actuated valve packages
PROJECT QUESTIONS

Industrial valve selection and supply

Explore custom engineered valves ↗

Ball, gate, globe and check valves

Start with the process duty: isolation, flow regulation or prevention of reverse flow. PIP reviews the required valve type alongside the medium, pressure, temperature, materials and end connections.

Floating, trunnion and DBB configurations

Include the required construction, pressure class and size in your enquiry. For double block and bleed assemblies or actuated packages, provide the isolation arrangement and control requirements.

What should I send for a valve quotation?

Send your valve list or datasheet, quantities, materials, pressure classes, connection standards and required documentation. Include the delivery location and requested schedule so the supply scope can be reviewed.
