Triple Offset Butterfly Valve (Butterfly Valve)

Butterfly valve has a simple structure, is easy to operate and widely used for flow path blocking and flow/pressure control. However, the disk surface of the valve is wider than that of other valves, and deflection of the disk is generated due to the working pressure. At this time, the disk is press-fitted into the seat ring like a wedge and, as a result, the operating torque is very high, causing a large impact sound and vibration when the valve is opened and closed.
In severe cases, the rotation axis of the valve may be distorted. In order to solve these problems, this product has a triple offset structure in which the shape of the disk is asymmetrical, so that when the valve is closed, the disk and seat ring is of the structure in line contact at the endpoint. Therefore, the airtight performance is excellent and there is hardly abrasion of the seat ring, which is a chronic problem of conventional products. The triple offset structure has drastically reduced noise and vibration resulting from high operating torque, which had been a problem in the conventional products, by dispersing the surface pressure acting on the disk surface in the system requiring high pressure (differential pressure) to the disk.

 

Easy V-Notch Ball Valve (V-Ball Valve)

The characteristics of the product are the flow control capability, which is an advantage of globe valves, and a simple structure that is a merit of ball valves. This product has solved the shortcomings of globe valves, which are expensive, relatively low flow rate, the cavitation phenomenon caused by the bent pipe and generation of noise and vibration, and the disadvantages of ball valves including sludge inflow between ball and body and seat ring breakage in the fluids containing fiber (paper pulp)-like sludge at the time of valve locking.
The Easy V-Notch Ball Valve has a seat ring installed on one side only, and the ball has a “V”-shaped notch to control the fluid to the EQ%. The shape of the “V” notch is designed to fit for the characteristics of fluids so that the control capacity can be changed according to such characteristics. In addition, due to the offset structure, the seat ring and the ball are in line contact at the closed end. Thus, the airtight performance is excellent and there is almost no abrasion of seat ring. As it is like a sharp cutter, “V” notch displays very favorable performance for use in fibrous piping lines like paper (pulp) line.

[INQ. NO. 1510M28] Prosave is a world class industrial valve manufacturer, specialized in manufacturing and supplying explosion relief valves for power plants, maritime plants and vessel plants.

https://korean-machinery.com///inquiry Prosave’s air release & vacuum breaker valve is mainly installed in power plants, water desalination plants, and maritime plants. Its main function is to control the air pressure in the pipe by releasing the air out of the pipe for the prevention of damage of the pipe and the pump. The product ensures surge and water-hammer protection, liquid overflow protection, and supply of high capacity venting for pipeline protection. It is supplied to leading conglomerates including Hyundai Heavy Industry.

Industrial-valves Prosave’s vacuum breaker valve is mainly installed in power plants, water desalination plants, and maritime plants. Its main function is to prevent damage by inpouring air in the atmosphere to pipes and tanks when it becomes a vacuumed state. It utilizes the latest technologies to provide protection against positive or vacuum over-pressure, prevent air intake, evaporative losses of product and help, and to eliminate odorous and potentially explosive vapor.

Prosave’s crankcase explosion relief valve is a valve that prevents explosion of a vessel’s diesel engine. It acquired product certification from MAN Diesel & Turbo, a multinational company based in Germany that produces large-bore diesel engines, and numerous classification bodies around the world and supplying them to the world’s major engine makers. This product’s benefits include perfect protection for fire explosion, quick opening and fully relieving pressure, and non-damaged stronger structure.
