1.Professional Quality Inspector.
From process to finished products of each order, inspectors must inspect every steps of every valve, including product appearance, dimensions and pressure testing. We will submit inspection reports to customers to ensure products quality 100% qualified.
2.High Production Capacity.
There are more than 50 lathes, 5 pressure testing machines, 15 assembling platforms , which could meet the needs in big quantities.
3.Variety Valves Types.
J-VALVES has variety valves types, materials, sizes, including ball valve, gate valve, globe valve, check valve & Y strainer. Manufactured in different standards and pressure and temperature to satisfy different demands fully.
4. Good Valves Material.
Valves materials' produce strictly according to international standards, such as physical properties and chemical component, which can tested by the third party or other organizations.
5.Complete Industrial Chain, Reasonable Price.
J-VALVES is located in industry center, it has complete industrial chain, which reduce production cost then make our price more reasonable and competitive.
6. Mature Technical Team.
We could suggest or design the most professional valves types as per customer's needs, such as temperature, fluid medium, pressure.
7.Fast After-sales Service.
When we receive after-sales requirements from customers, we will help to solve problems at the first time, and try to satisfy customers within 24 hours.
8.Close to Sea Port, Fast Delivery.
Wenzhou city is closed to Ningbo and Shanghai sea port, it is convenient for delivery, many sea routes, order ship fast.

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 -196ºC 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.
