J-VALVES High Performance Industrial Valves are Suitable for Various Harsh Environments


Product Introduction


Our High Pressure Forged Steel Worm Gear Operated Trunnion Flange Ball Valves are engineered for heavy-duty industrial use. The forged steel body ensures high strength and corrosion resistance, while the trunnion-mounted ball design reduces stem friction for smooth operation. The worm gear operator provides reliable, low-torque actuation with self-locking safety. Featuring dual soft/metal-to-metal seals and fire-safe compliance (API 607), these valves meet API 6D and ASME standards. Ideal for oil & gas, chemical, and power sectors, their flange connections (ASME B16.5) enable easy pipeline integration for secure on/off control.

Advantages:


  1. Superior Pressure Resistance: Built with forged steel construction, these valves handle high-pressure systems up to Class 2500, ensuring structural integrity in extreme conditions. The solid body design minimizes deformation risks, making them reliable for heavy-duty applications in oil refineries and gas transmission.


  2. Effortless Worm Gear Actuation: The precision worm gear operator delivers smooth, low-effort operation, reducing manual labor and enabling precise flow control. Its self-locking mechanism prevents unintentional movement, enhancing safety, while the gear ratio amplifies torque for large-diameter valves.


  3. Dual Sealing Reliability: Featuring both soft (PTFE/VITON) and metal-to-metal seals, these valves guarantee bubble-tight shut-off in both directions. The double-block-and-bleed (DBB) capability adds an extra layer of safety for pipeline isolation and maintenance.


  4. Trunnion-Mounted Efficiency: The trunnion design supports the ball at both ends, reducing stem stress and friction during operation. This results in lower torque requirements, extended seal life, and consistent performance even after frequent cycling.


  5. Corrosion & Wear Resistance: The forged steel body, combined with hard-facing options for the ball and seats, offers exceptional resistance to abrasion, erosion, and chemical corrosion. Ideal for harsh media like sour gas or abrasive fluids, ensuring long service life with minimal maintenance.


  6. Versatile & Compliant Design: Compliant with API 6D, ASME, and ISO standards, these valves feature flange connections (ASME B16.5) for easy installation across global industries. Optional accessories like position indicators and limit switches enable integration with PLC systems, enhancing operational flexibility.

Advantages
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 -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.
