05 / VALVE Kv / Cv CALCULATOR
Calculate Your Required Cv Before Requesting a Quote
Liquid flow coefficient and line velocity from flow rate, pressure drop and specific gravity. Useful for early control valve and line-size checks.
Kv = Q × √(SG ÷ ΔP)
Cv = 1.156 × Kv
Velocity = Q ÷ (3600 × π/4 × ID²)
Cv = 1.156 × Kv
Velocity = Q ÷ (3600 × π/4 × ID²)
REQUIRED Kv (m³/h at 1 bar)0.0Kv
REQUIRED Cv (US gpm at 1 psi)0.0Cv
LINE VELOCITY0.00m/s
FLOW RATE IN US GPM0.0gpm
For incompressible liquids in turbulent, non-cavitating, non-flashing flow only. Gas, steam, two-phase and viscous service need a full sizing method to IEC 60534. Compare velocity with your line-sizing criteria. Send the valve list for a quotation →

12 / VALVES SUPPLIER IN THE UAE
Industrial valves supplier and stockist in Abu Dhabi and Dubai.
Gasify Middle East Trading LLC is a UAE-based industrial supplier and stockist of gate valves, globe valves, check valves, ball valves, butterfly valves, plug valves, needle valves, safety relief valves and actuated valves. From offices in Abu Dhabi and Dubai we support EPC contractors, fabricators, plant procurement teams and project owners in oil and gas, petrochemical, refining, power generation, water and infrastructure.
Our valve range covers cast steel valves to API 600, forged steel valves to API 602, pipeline ball valves to API 6D, metal ball valves to API 608, butterfly valves to API 609 and check valves to API 594. We source the sizes, pressure classes, body materials, trim and end connections your piping material class requires, and supply them with the pressure test reports and material certificates the order calls for.
ADNOC valve supplier and Saudi Aramco valve supplier support
Projects in the UAE, Saudi Arabia and the wider GCC often reference ADNOC or Saudi Aramco specifications, approved manufacturer lists and inspection requirements. Gasify reviews these requirements against the valves you need, coordinates the documentation and inspection called for by the order, and supports the RFQ from technical clarification to delivery. Approval status is never assumed. Requirements are confirmed against each project's documents.
Gate, globe and check valve supplier for oil and gas
For hydrocarbon, steam and utility service we supply gate, globe and check valves in ASTM A216 WCB, A105, A352 LCC and A217 WC6/WC9, with 13Cr, Stellite-faced and stainless trim. Forged steel valves to API 602 in Class 800 and 1500 cover small-bore isolation, drains, vents and instrument connections, while cast steel valves cover line sizes up to large-bore.
API 6D ball valve supplier and trunnion mounted ball valves
Floating, trunnion-mounted, top-entry and cryogenic ball valves are supplied to API 6D, API 608 and ISO 17292 with soft or metal seats, fire-safe design and fugitive emission options. Ball valves can be supplied manual, gear-operated or as complete pneumatic, electric or hydraulic actuated assemblies for ESD and remote isolation duty.
Stainless steel, duplex, low-temperature and cryogenic valves
For corrosive, chloride and seawater service we source stainless steel valves in CF8M and F316, and duplex and super duplex valves in A995 and A182 F51, F53 and F55. Low-temperature carbon steel valves in LCC and LF2 and extended-bonnet cryogenic valves are available where the datasheet specifies the minimum design temperature and testing requirements.
Butterfly, plug, needle and safety relief valves
Concentric, double-offset and triple-offset butterfly valves cover water, firewater and hydrocarbon lines. Plug valves, needle valves and double block and bleed valves serve gas distribution, sampling and instrument lines, and pressure safety valves are sourced to API 526 against your process data sheet.
Valves with pipes, fittings and flanges in one package
Valves rarely travel alone. Gasify can consolidate valves with steel pipes, butt weld and forged fittings and ASME flanges in a single package, with phased deliveries to the UAE, GCC, Middle East, Africa and South Asia. Explore how we work on our project supply page or read about oil and gas supply.
13 / FAQ
Industrial valve supply questions.
Are you an industrial valves supplier and stockist in the UAE?
Gasify combines UAE-based supplier and stockist support with international manufacturer sourcing. Availability depends on valve type, size, pressure class, body material and quantity, so current stock is confirmed for each RFQ.
Can you supply valves to ADNOC and Saudi Aramco project specifications?
Gasify supports procurement against project valve data sheets, piping classes and client specifications, including ADNOC and Saudi Aramco requirements where the project calls for them. Approved manufacturer and vendor list requirements are reviewed for each project. Gasify does not represent an approval status unless it is formally documented.
Which types of industrial valves do you supply?
The range covers gate, globe, check, ball, butterfly, plug and needle valves, double block and bleed valves, pressure safety valves, control valves, and actuated and emergency shutdown valves in carbon, low-temperature, alloy, stainless, duplex and nickel alloy materials.
What is the difference between API 600, API 602, API 6D and API 608 valves?
API 600 covers bolted-bonnet cast steel gate valves. API 602 covers compact forged steel gate, globe and check valves in small sizes. API 6D covers pipeline valves, including trunnion ball, check, gate and plug valves. API 608 covers metal ball valves in flanged, threaded and welded-end designs.
What is the difference between a floating and a trunnion-mounted ball valve?
In a floating ball valve, line pressure pushes the ball against the downstream seat to seal, which suits small and medium bores and lower pressure classes. A trunnion-mounted ball valve holds the ball on fixed trunnions and uses spring-loaded seats, which lowers operating torque and suits large-bore and high-pressure service.
Which valve body materials are available?
Carbon steel (A216 WCB, A105), low-temperature steel (A352 LCB/LCC, A350 LF2), chrome-moly (A217 WC6/WC9/C12A, A182 F11/F22/F91), stainless (A351 CF8M, A182 F316), duplex and super duplex (A995, A182 F51/F53/F55) and nickel alloys are sourced against the project material specification.
Do you supply NACE MR0175 / ISO 15156 sour service valves?
Sour service valves can be sourced where the project specification requires them, including material and hardness limits, NACE-compliant bolting and the documentation stated on the valve data sheet. Requirements are confirmed before quotation.
What tests and certificates come with the valves?
Valves are supplied with EN 10204 3.1 material certificates and pressure test reports to API 598, API 6D or ISO 5208, as the order requires. Fire-safe and fugitive emission type-test evidence, EN 10204 3.2 certification and third-party inspection can be coordinated where the project specifies them.
Do you supply actuated, control and ESD valves?
Yes. Pneumatic, electric and hydraulic actuated valves, control valves and emergency shutdown valves are available as complete assemblies, with positioners, solenoids and limit switches in hazardous-area housings where required.
Can you supply cryogenic and low-temperature valves?
Yes. Extended-bonnet cryogenic ball, gate, globe and check valves and impact-tested low-temperature valves are sourced where the datasheet specifies the minimum design temperature and testing requirements.
How do I request a quotation for valves?
Send your valve list, MTO, BOQ or data sheets with valve type, size (NPS), pressure class, body and trim material, end connections, operator, design standard, test and certificate requirements, quantity and delivery location. The procurement team reviews the requirement and responds with a quotation.
