Superior Corrosion Resistance for Harsh Environments
Constructed from C95800 nickel aluminum bronze, this PRV resists chloride stress corrosion in seawater, sulfuric acid in chemical processing, and alkaline media, delivering over 20 years of reliable service in offshore platforms, desalination plants, and marine applications without pitting or degradation.

Precision Pressure Regulation with Rapid Response
Engineered to maintain downstream pressure within ±2% accuracy, the direct-acting diaphragm design reacts to fluctuations in 0.1 seconds, protecting sensitive equipment like LNG storage tanks, pharmaceutical reactors, and steam turbines from overpressure damage across flow rates from 0.2 to 25 bar.

Factory-Direct Customization for Tailored Solutions
Eliminating intermediaries, the valve offers 20-30% cost savings while allowing customization of pressure ranges (0.02-25 bar via spring adjustments), connection types (flanged, threaded, welded), actuator options (manual, pneumatic, electric), and seals (PTFE, EPDM, etc) to meet specific industrial requirements without additional engineering fees.

Multi-Industry Versatility for Diverse Applications
Suitable for oil & gas (subsea wellheads, crude pipeline pressure reduction), chemical (acid transfer, reactor control), marine (shipboard seawater systems, LNG bunkering), and power (steam turbines, cooling water networks), its robust design adapts to high-pressure, high-corrosion environments across global industrial sectors.

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.
