2-Way Valves :
What is a 2-Way Valve?
A 2-way valve is the most common and fundamental type of valve, designed to control fluid flow by either completely stopping it or allowing it to pass through. Unlike its more complex counterparts, a 2-way valve has just two ports: one inlet and one outlet. Its function is straightforward, acting as a simple on/off switch for fluid flow in a pipe. This makes it an essential component in a vast range of applications, from residential plumbing to large-scale industrial processes.
The primary function of a 2-way valve is to isolate a specific section of a piping system. When closed, it forms a tight seal to prevent any fluid from passing, effectively shutting off a line. When open, it allows fluid to flow freely. The internal mechanism that controls this flow can vary greatly. Examples include ball valves, which use a rotating sphere with a hole to control flow; gate valves, which use a flat gate that is raised and lowered; and globe valves, which use a plug to regulate flow. Each type offers different advantages in terms of pressure drop, flow control, and sealing capability.
These valves are made from a variety of materials, including brass, stainless steel, PVC, and cast iron, with the choice of material depending on the application's specific requirements. Factors such as the type of fluid, its pressure, temperature, and chemical properties all influence the best material for the job.
The core benefit of a 2-way valve is its simplicity and reliability. Its direct function makes it the perfect solution for tasks that only require turning a flow on or off. This makes it a cornerstone component in everything from a simple household faucet to sophisticated industrial control systems.

Premium 2-Way Valves with Leak-Proof Seals
Welcome to HANUMAN, your premier destination for high-quality automation solutions in China, specializing in process valves, including 2-way valves with leak-proof seals.
Established in 2020 and headquartered in Ningbo, Zhejiang, China, HANUMAN is a rapidly expanding factory of famous automation. As a subsidiary of the esteemed XINGYU GROUP, which boasts nearly 30 years of experience in pneumatic and hydraulic systems, HANUMAN (also referred to as GXR) leverages extensive industry resources to provide top-tier air and flow control solutions globally. Our commitment to excellence drives us to continuously explore new opportunities and expand our product range.
When it comes to 2-way valves with leak-proof seals, HANUMAN offers a diverse portfolio designed for various industrial applications:
- 2L Series:These high-temperature direct 2-way normal closed steam water solenoid valves are widely used in automatic control systems, including pneumatic, hydraulic, water supply, and air conditioning systems. They adopt PTFE sealing material, which is particularly suitable for high-temperature fluids and greatly extends the valve body's service life due to the top structure and automatic seal compensation.
- VQ21A Series:These compact and lightweight two-way pilot operated solenoid valves for drying air are known for their high operating frequency, long service life, and high-speed response time.
- SB115 Series:These brass water electron solenoid control valves are direct-acting, normally closed, with sensitive action and low noise. They offer various flow apertures and have a protection level up to IP65, with NBR or VITON oil seal materials.
- SB116 Series:These brass 2-position, 2-way direct-acting water solenoid valves are designed for stable operation with low noise and no water hammer impact. They are applicable to various media like water, oil, weak alkali, gas, and liquefied gas, and can operate below 90℃ with zero pressure start.
- Solenoid Operated Diaphragm Valves (2W/PU Series):These valves are specifically engineered for precise control of fluid handling. They feature a direct-acting diaphragm structure that allows starting without pressure, expanding their application field. The use of plastic-sealed coils enhances safety in many environments, and their flat diaphragm structure ensures reliable opening and closing, increasing product service life. The diaphragm, made of highly elastic rubber or plastic, ensures excellent sealing performance by closely fitting the valve seat, effectively preventing fluid leakage. This makes them an ideal choice for precise fluid control, offering durability, reliability, and suitability for corrosive, high-temperature, and high-pressure environments.
- 2S Series:These stainless steel normally closed large orifice solenoid valves also feature a direct-acting diaphragm structure and can start without pressure, with brass or stainless steel body options and PTFE oil seal material.
- XSA Series:These high vacuum solenoid valves are two-way, normal closed, and feature flame resistance conforming to UL94V-0 standard. They offer optional electrical entry types and various rated voltages and thread types.
Our 2-way valves with leak-proof seals are crucial for achieving energy efficiency and system reliability in industrial automation. The robust design and quality materials used, such as PTFE and NBR/VITON sealing materials, ensure that our valves maintain a tight seal, preventing fluid leakage and contributing significantly to the overall efficiency of industrial processes.
Beyond our standard product offerings, HANUMAN's strong technical team provides OEM and ODM services, allowing us to create customized solutions tailored to your specific requirements.
