Innovative valve solutions for industry

- Closed Coupled Solutions -
Measuring Flow, Pressure and Temperature

Qvalve, scalable solutions complying to customers exact needs. Our engineers with over 30 years of experience developed a platform providing solution for non-standard valves become standard.

 A range of Double Block and Bleed valves on a single design has been developed, covering a wide range of specifications and demands. This comprehends bore size up to 14mm, exotic materials and a variety of process connections. Overall results in better accuracy, reduced weight, space saving, easy maintenance and low operational cost.

    ANSI B16.5, B16.36 and B16.34 requirements
  • Size DN15 (1/2”) up to DN50 (2”)
  • Pressure rating 150 lbs up to 2500 lbs 
  • Bi-directional, Bubble tight 
  • 6, 10,1/2" & 14mm bore for ball valves 
  • 5mm bore for needle valves 
  • End connections (ASME, DIN, etc)
    Flange, Butt/Socket weld, Threaded, others
  • Seat - Metal and Soft seated 
  • Seal - FE seals, Graphite, Peek, PVX, PCTFE, PTFE (Reinforced), others

Quality

  • Low torque operation, all pressure classes
  • Ball valve seat and seal design ensures bubble-tight seal at high and low pressure
  • Needle valve design ensures non‑rotating tip with bubble tight seal 

    In-house Test
  • Each valve 100% pressure tested at 1.5 working pressure 
  • All valves certified to EN10204 3.1 as standard, 
  • EN10204 3.2 optional

Emission

  • Fugitive emission ISO 15848- 1,  API 624, API 641
  • Fewer number of joints reduces risk of external process leakage
  • No need for Impulse lines, manifold brackets and mounting pillars.

    Optional
  • Shell MESC SPE 77/312 / DVT
  • High/low pressure gas testing
  • Dye penetrant, Ultrasonic, PMI and Ferrite testing

Safety

  • Safety, reliability and durability are the fundamentals of our design.
  • Our manufacturing ensures close control of the manufactured products. 
  • Each valve is subjected to our rigorous in-house testing procedure.
  • Blow-out proof stems and needles with backseat facility 
  • Sealing arrangement protects all internal threads from process media 
  • Fire safe & Anti-static to BS 5351
