Resilient seated concentric butterfly valve is a butterfly valve without eccentricity. The valve is concentric with the pipeline and the valve disc is fixed at the center of the valve, suitable for use between ASME Class 125 and Class 150 flanges. Typical valve seat materials include EPDM rubber, nitrile rubber, polytetrafluoroethylene, natural rubber, etc. In addition, the lined butterfly valve is also concentric with the pipeline and designed specifically for harsh chemical media. The characteristics of the soft sealing valve seat of the resilient seated concentric butterfly valve limit its applicability to pipeline systems with medium temperatures between -40 ℃ and 150 ℃, and pressures between 0.6MPa and 1.6MPa.

The Wafer Concentric Butterfly Valve offers reliable performance in various industrial applications. Its compact design and wafer-style body make installation simple and cost-effective. With a concentric disc design, this valve ensures a tight seal, reducing the risk of leaks.

Wafer Type Butterfly Valve

The characteristic of a lug type butterfly valve is its threaded hole design. The threaded hole design can make lug butterfly valve more stable during operation. Lug type butterfly valves are suitable for pipeline end services.

Lug Type Butterfly Valve

U-section butterfly valves, also known as short structure flange butterfly valves, have a relatively short structural length and are connected in a similar way to wafer or lug butterfly valves. This type of butterfly valve has a small volume, light weight, and good adjustment performance, making it very convenient and fast to operate during the switching process.

U-section Butterfly Valve

Resilent seated gate valve is one of the most critical components in water system pipelines. They are crucial for controlling water flow and pressure, and play an important role in safety. Resilient seated gate valves can be used for many years without requiring any maintenance.

A cast iron strainer is a device that removes impurities from pipelines through its mesh filtering element. To protect expensive machinery from potential damage caused by foreign particles carried by process fluids and reduce maintenance and downtime. In order to protect expensive and important downstream equipment such as pumps, flow meters, drain valves, control valves, etc., it is necessary to use the correct filters in the correct positions.

Foot valve is a special type of check valve, with a filter fixed at the open end. Foot valves are widely used in pump suction or at the bottom of pipelines. Even when the pump is in the open state, the bottom valve can avoid medium backflow during use, making it an ideal choice for pipeline applications in wells, ponds, and pools.

Cast Iron Foot Valve

When a trunnion mounted ball valve is in operation, all the force generated by the fluid pressure in front of the valve on the ball is transmitted to the bearing, which will not cause the ball to move towards the valve seat. Therefore, the valve seat will not bear excessive pressure. Therefore, the torque of the fixed ball valve is small, the deformation of the valve seat is small, the sealing performance is stable, and the service life is long. It is suitable for high-pressure and large-diameter situations.

Forged Steel Trunnion Ball Valve

Cast steel floating ball valves play a crucial role in industrial fluid control systems, renowned for their reliability, durability, and versatility. These valves are manufactured using high-quality cast steel, ensuring robustness and resistance to corrosion, erosion, and extreme temperatures.

DIN Floating Ball Valve

The opening and closing component of a metal seated wedged gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape, and the wedge angle varies with the valve parameters

DIN Wedged Gate Valve

The opening and closing component of a bellows pipe globe valve is a plug shaped valve disc, with a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the fluid. The movement form of the valve stem can be either the lifting rod type or the concealed rod type. The bellows sealed globe valve is only suitable for fully open and fully closed, and cannot be adjusted or throttled.

Angle Type Bellows Globe Valve

The bellows pipe, valve cover, and valve stem of the bellows sealed gate valve are welded together without any seams, so there is no leakage. The action of the valve stem is caused by the deformation of the compressed corrugated pipe, not by relative motion. Ordinary gate valves are sealed with disc material, which slides between the valve stem and disc material, making them prone to leakage at low temperatures (valve core). Bellows do not have this problem.

Bellows Sealed Gate Valve

The steam shut-off valve (also known as the "bellows pipe shut-off valve") adopts a double-layer bellows pipe design and is welded to the valve stem to maintain stable operating performance, avoiding valve stem vibration caused by valve plug vibration.
