Manual Valve Standards & Specifications: A Technical Reference
Manual Valve Standards & Specifications: A Technical Reference
When procuring industrial valves for critical systems, engineers and procurement professionals need clear, verifiable data on certifications, material grades, pressure classes, and design standards. This reference page consolidates the key technical specifications and global certifications for manual valves manufactured by EG Valves, a professional valve manufacturer established in 2000 with a 27,500 m² facility and an annual output of 90,000 pieces.
Problem Definition: What Makes Manual Valve Selection Complex?
Selecting the correct manual valve for a given application involves matching multiple parameters: body material, pressure rating, end connection type, seat material, and applicable industry standards. A mismatch can lead to premature failure, leakage, or safety hazards. Buyers often struggle to cross-reference product specifications with required certifications such as API 600, API 6D, or PED. This guide provides a fact-based reference to simplify that process.
Industry Background: The Manual Valve Market
The global manual valve market was estimated at USD 78.4 billion in 2025 and is projected to reach USD 117.17 billion by 2035 (Vantage Market Research). Within this market, manual ball valves held a 28.1% share in 2025 (Precedence Research), while the manual segment led the global butterfly valve market with a 41.2% revenue share in 2024 (Grand View Research). These figures underline the dominance of manually operated valves in industrial fluid control. EG Valves produces a comprehensive range of manual gate valves, globe valves, ball valves, butterfly valves, check valves, and plug valves compliant with ANSI, DIN, BS, and JIS standards.
Detailed Solution: EG Valves Manual Valve Portfolio
All valves from EG Valves are manufactured under ISO 9001-certified processes. The factories have obtained API 600, API 6D, CE, and PED certifications. These certifications apply across the product line, ensuring compliance with global market requirements. Below is a breakdown of the key manual valve types and their essential parameters.
Manual Gate Valves
EG Valves manufactures cast iron gate valves (model GTI001) in sizes NPS 1-1/2" to 48", pressure ratings Class 125/150, with flanged ends (FF, RF). The cast steel gate valve (model GTS019) covers Class 150 to Class 1500, sizes up to 48", and is available in carbon steel, stainless steel, and alloy steel. For high-pressure applications, the forged steel gate valve (model GTF023) offers Class 800 to Class 2500, sizes NPS 1/2" to 2-1/2". The pressure seal gate valve (model GTP002) is designed for power plant and high-temperature services, with ratings up to Class 2500 and sizes up to 60".
Manual Ball Valves
The threaded ball valve (model BVS213) covers NPS 1/2" to 4", pressure 1000 PSI, with NPT, BSP, or BSPT ends. Cast steel floating ball valves (model BVF206) range from Class 150 to Class 600, sizes NPS 1/2" to 12". For larger diameters and higher pressures, the cast steel trunnion ball valve (model BVT207) supports Class 150 to Class 1500, sizes up to 40". The forged steel trunnion ball valve (model BVF209) reaches Class 2500, sizes up to 36". All ball valves feature blow-out proof stems, fire-safe design, and anti-static devices.
Manual Butterfly Valves
EG Valves offers resilient seated butterfly valves (model BTV300) in wafer, lug, and double flange types, sizes NPS 1-1/2" to 48", pressure Class 125/150. The PTFE lined butterfly valve (model BTF301) provides excellent anti-corrosive performance for chemical service. High performance butterfly valves (model BPV302) handle Class 150 to Class 600, while triple offset butterfly valves (model BOV303) are available up to Class 600 and sizes up to 60" for demanding applications such as refining and oil & gas.
Manual Globe Valves
Globe valves from EG Valves include cast iron (model GLI101), cast steel (model GLS105), and forged steel (model GLF109) variants. The cast steel globe valve covers Class 150 to Class 1500, sizes NPS 1-1/2" to 24". Forged steel globe valves (model GLF109) are rated Class 800 to Class 2500. Below-seal globe valves (model GLB107) provide double-seal capability for demanding fluids.
Manual Check Valves and Strainers
Check valves include cast iron swing/wafer types (model CVI405), cast steel (model CVS407), forged steel (model CVF409), and stainless steel (model CSV410) in sizes up to 48" and pressure classes up to Class 1500. Strainers (Y-type and basket) are available in cast iron, cast steel, and threaded configurations.
Step-by-Step Selection Breakdown
- Define service conditions: Fluid type, temperature, pressure, and corrosivity.
- Select valve type: Gate for isolation, globe for throttling, ball for quick shut-off, butterfly for large-diameter low-pressure, check for backflow prevention.
- Match pressure class: Choose from Class 125 to Class 2500 based on system design.
- Choose end connections: Flanged (RF, FF, RTJ), threaded (NPT/BSP), socket weld, or butt weld.
- Verify certifications: Ensure ISO 9001, and where required, API 600/6D, PED/CE, ISO45001.
- Confirm material compatibility: Carbon steel, stainless steel, duplex, alloy steel, or lined options.
Use Cases for Manual Valves
- Oil & Gas: Cast steel gate and trunnion ball valves certified to API-6D and API-600 for high-pressure pipelines.
- Water Treatment: Cast iron gate and resilient seated butterfly valves for isolation and flow control.
- Chemical Processing: PTFE lined butterfly valves and stainless steel ball/globe valves for corrosive fluids.
- Power Generation: Pressure seal gate and globe valves for high-temperature steam services.
