The Comprehensive Guide to Manual Valves: Types, Applications, and Selection
The Comprehensive Guide to Manual Valves: Types, Applications, and Selection for Industrial Pipelines
Manual valves are fundamental components in industrial fluid control systems, providing reliable on/off and throttling functions without the need for external power sources. 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, driven by demand across oil & gas, water treatment, chemical, power generation, and mining industries. EG Valves Manufacturing Co., Ltd., established in 2000, is a professional valve manufacturer specializing in R&D, manufacturing, and exporting a wide range of industrial manual valves, including gate valves, globe valves, ball valves, butterfly valves, check valves, and plug valves.
What Is a Manual Valve?
A manual valve is a mechanical device that regulates fluid flow by hand operation—typically via a handwheel, lever, or gearbox. It does not rely on pneumatic, electric, or hydraulic actuators, making it cost-effective, simple to maintain, and ideal for applications where automated control is unnecessary or where reliability must be maximized. Manual valves are available in numerous designs to suit different pressures, temperatures, and media.
Problem Definition: Choosing the Right Manual Valve for Your Application
When specifying a manual valve, engineers and procurement professionals must consider factors such as media type, pressure rating, temperature, end connections, material compatibility, and installation space. Selecting the wrong valve type can lead to leakage, premature wear, or system failure. Understanding the key characteristics of each valve category is essential to making an informed decision.
Industry Background
Manual valves are widely used across industries. In 2024, the manual butterfly valve segment led the global butterfly valve market with a 41.2% revenue share due to cost-effectiveness and simplicity. Manual ball valves dominated the general valve market with a 28.1% share in 2025, driven by reliability in high-pressure applications. The global gate valve market was valued at USD 13.0 billion in 2024, projected to reach USD 20.6 billion by 2034. Wafer-type manual butterfly valves held the largest configuration share (38.5%) in 2025 due to compact design and cost efficiency.
EG Valves: A Trusted Manufacturer of Manual Valves
EG Valves Manufacturing Co., Ltd. operates from a 27,500 m² facility with approximately 300 employees and an annual production capacity of about 90,000 units. The company's R&D team consists of 30 engineers. All valves are manufactured under ISO 9001-certified processes, and the factories have obtained API 600, API 6D, CE, and PED certifications. EG Valves exports to 33+ countries in Europe, North America, Latin America, and the Middle East, with an export ratio of 80%.
Step-by-Step Manual Valve Selection Process
- Identify the application and media – Water, oil, gas, steam, corrosive chemicals? Each media requires specific materials and seat types.
- Determine pressure and temperature requirements – Choose a valve with an appropriate pressure class (e.g., Class 150, Class 300, PN10, PN16).
- Select the valve type – Gate valves for on/off with minimal pressure drop; globe valves for throttling; ball valves for quick quarter-turn shutoff; butterfly valves for large-diameter, low-pressure service; check valves to prevent backflow; plug valves for multiport diversion.
- Choose end connections – Flanged (RF, FF), threaded (NPT, BSP, BSPT), wafer, lug, or butt-weld.
- Verify compliance with standards – ASME B16.34 for pressure-temperature ratings, API 600 for heavy-duty gate valves, etc.
Use Cases Across Industries
EG Valves serve the power, mining, refining, oil & gas, water and wastewater treatment, pulp and paper, chemical, and petrochemical industries. For example, in paper and pulp plants, knife gate valves with wide flow channels handle fibrous media. In water treatment, resilient-seated butterfly valves (e.g., model BTV300 with EPDM seat) are common. For high-pressure oil & gas pipelines, forged steel trunnion ball valves and through conduit gate valves are preferred.
Comparison of Manual Valve Types
| Valve Type | Typical Sizes | Pressure Range | Primary Use | Example Model |
|---|---|---|---|---|
| Gate Valve | NPS 1/2" – 48" | Class 125 – 2500 | On/off, low pressure drop | GTI001 (Cast Iron) |
| Globe Valve | NPS 1/2" – 24" | Class 125 – 1500 | Throttling, frequent operation | GLS105 (Cast Steel) |
| Ball Valve | NPS 1/2" – 60" | Class 150 – 2500 | Quick shutoff, high pressure | BVF206 (Floating) |
| Butterfly Valve | NPS 1-1/2" – 60" | Class 125 – 600 | Large diameter, low cost | BTV300 (Resilient Seated) |
| Check Valve | NPS 1/2" – 48" | Class 150 – 1500 | Prevent backflow | CSV410 (Stainless Steel) |
| Plug Valve | NPS 2" – 40" | Class 150 – 1500 | Multiport diversion | PLV600 |
Frequently Asked Questions About Manual Valves
What standards apply to manual industrial valves?
Industrial manual valves must comply with ASME B16.34 for pressure-temperature ratings and wall thickness. For heavy-duty bolted-bonnet steel gate valves in the petroleum and natural gas industries, API 600 is the specific standard. EG Valves manufactures to ANSI, DIN, BS, and JIS standards, with API 600, API 6D, CE, and PED certifications obtained for relevant products.
What is a manual floating ball valve?
A manual floating ball valve uses a ball that is not fixed in position; line pressure pushes the ball against the downstream seat to create a seal. EG Valves offers the Cast Steel Floating Ball Valve, model BVF206, with sizes from NPS 1/2" to 12", pressure rating Class 150 to Class 600, and manual operation via handle lever. It is suitable for oil & gas, petrochemical, power generation, and water treatment.
What is the pressure rating of a manual butterfly valve?
EG Valves' manual butterfly valves, such as the Resilient Seated Butterfly Valve (model BTV300), are available in pressure ratings Class 125/Class 150 or PN6/PN10/PN16. Sizes range from NPS 1-1/2" to 48". Wafer type, lug type, and double flange types are all available with handle lever or gearbox operation.
