Material Advantages
High - quality forged steel
The F304 stainless steel offers good corrosion resistance, ensuring the valve can operate in various environments without being affected by rust or other forms of corrosion.
The material's ability to maintain its mechanical properties at low temperatures is crucial for cryogenic applications. It can withstand the extreme cold without losing its strength, ensuring the valve's long - term performance and reliability.

Performance and reliability
In cryogenic applications, the valve's ability to perform well at low temperatures is crucial. The F304 stainless steel used in the valve has excellent low - temperature performance. It can maintain its mechanical properties and sealing ability even at extremely low temperatures. This is important for preventing leaks and ensuring the safe operation of the valve in cryogenic environments.
 

Rising stem design
The rising stem design of the gate valve provides clear indication of the valve's position. As the stem rises, it shows that the valve is open, and when it lowers, the valve is closed. This visual cue is important for easy operation and monitoring.
The design also allows for precise control of the valve's opening and closing. The stem's movement is smooth, enabling accurate adjustment of the flow rate. This is essential for applications where the flow needs to be carefully regulated.

ANSI standards
The valve adheres to ANSI standards, which ensure high - quality and reliable performance. ANSI standards cover various aspects of valve design, construction, and operation. By following these standards, the valve meets the requirements of international regulations and industry best practices.
The ANSI standards also provide guidelines for the testing and inspection of the valve. This ensures that the valve meets the required quality and performance standards before it is released for use.

FAQ

FAQ

1. How to guarantee your quality? When we install, if there is some quality problems, how to solve it?
We have QC department, quality inspector will check every step when processing and make reports to clients for checking. If any quality problems, we will check and reply you within 24 hours to solve it. Please contact us for any quality problems.

2. What's the temperature and pressure for valves?
For metal seat, temperature range from -196ºC to 425ºC. For soft seat ball valve, temperature range from -29ºC to 200ºC. Pressure range from PN6 to PN420(150LB~2500LB).

3. What's the materials of valves?
Stainless Steel, Forged Stainless Steel, Alloy Steel, Duplex Steel, Titanium Alloy, Nickel-aluminum, Bronze Alloy, etc. Details materials requirements could consult us at any time.

4. How about delivery time?
Our factory is near to Ningbo & Shanghai seaport, generally speaking, export to Asia takes about 7-10 days, export to Europe, Middle East, Africa, North America, South America, etc. takes about 30-35 days by sea.

5. What's the medium for your valves?
Mostly are used in water, gas and oil. When inquiry, it is better to offer your medium, we could suggest materials and valves type for clients.

6. Can ball valves regulate medium?
No, ball valves only can not use for regulating, it is a kind of isolating valve.

7. What are the quarter turn valves?
Ball valve, Butterfly Valve, and Plug valve are rotary motion control valves. They just need a quarter turn to come into action.

8. What's the direction of valves?
Ball Valve and gate valve are bi-directional valves, globe valve, check valve and y strainer have arrow on valve body to indicate direction.

9. What's the difference between rising stem and non-rising stem of gate valve?
The rising stem gate valve can be seen from the appearance whether the valve is closed or open. The lead screw can be seen while the non-rising stem gate valve can not. Non-rising stem gate valve handwheel will go and up when rotate handwheel, rising stem gate valve will not. And The rising stem gate valve requires a larger installation space because of the stem; the height of the Non-rising stem gate valve is small, and it will not take up too much space during installation.

10. What's the difference of gate valve and globe valve?
Gate valve is bi-directional valve, globe valve in single way valve and has fixed direction when install. And globe valve has better sealing than gate valve, when globe valve close, fluid medium add pressure on disc to keep better sealing. Gate Valve wedge is parallel with flange, when close, both side fluid medium add pressure on wedge.

11. Check Valve Introduce.
Check Valve is unidirectional valve, also called one way valve, non-return valve. Because medium flow decide its direction. It has swing type, lift type(piston and ball), vertical type, butterfly type. Wafer type check valve has three types, spring return type, single disc type and double disc type. Anyway, could choose valve type according to medium, pressure and temperature. Masoneilan Valve will give you the best suggestions.

12. What's the type of butterfly Valve?
Generally speaking, for connection ends, butterfly valve has lug type, wafer type, double flange type; for design structure, butterfly valve has concentric type, double eccentric type, triple eccentric type.
