SMC BALL VALVE

Prevention of product damage and screw abrasion through the improvement of the durability of the resin in the area the largest force is applied by putting metal reinforcements into the inside of the shaft.

eliminate friction by leaving a gap between the ball and matrix and, by strengthening the watertightness by putting an O-ring between them instead, to prevent the ball and matrix from being worn and to use after a simple repair or replacement of the defective part.

First SMC Ball Valve in the world

Strengths of FRP (Corrosion resistance, heat insulation, lightweight and low heat deformation rate)

-All development has been ended in a failure due to the above strengths even a lot of trials have been made.

-Valve finally succeeded in the development of the product for the first time in the world by overcoming the same failure experiences.

Core Technologies

Core Technologies

Excellent in productivity and cost savings in logistics and inventory control as a molded product unnecessary to take a finishing process

-developed a resin resistant to a pure hydrochloric acid for the first time in the world.-Excellent in chemical resistance through the melting of thermo-hardening resin (SMC) and heat press foaming

Acid Resistant

Durability-Developed a ball valve not frozen and burst for the first time in the world.-Rated as excellent in abrasion resistance more than 3 times more than PVC valve proved in the durability and vibration resistance test

excellent in economics and suitable for use in shipbuilding, construction of building, etc. as it is lightweight of 1/5 of an existing metal valve, suitable for use in the sea-bed as it is salt resistant and suitable to be used as an underwater valve as it is rust free.

Core Technology -1

1) Yoke part: It, through the design to combine H-beam shape and ribs for preventing yoke deformation together, prevents a crack produced due to a concentrated load by evenly spreading the load applied when an equipment is operating and realizes the extension of a product life by minimizing the deformation developed by aging even use for a long time. According to the outcome from our internal test, it satisfied the run of 1.6 million times and this product is currently under the durability test by a Japanese company.

2) Yoke pin assembly: Apart from the way of forcible insertion, it is designed the pin is assembled smoothly and the rupture of the driving yoke is prevented and the loss of the pin is also permanently prevented at the same time by placing a retaining ring.

3) Guide ring and pad: It enables to keep the best operation condition for a certain period of time without applying lubricant by adding molybdenum to the material to make operation smooth and a clip feature has been also added in order to prevent the accessories from falling off.

4) Crank and shaft: By adopting a broach method different from the existing press method in order to increase the precision in the operation, the flow tolerance and driving noise has been drastically reduced and the product life has been extended.

5) the symmetry design of all parts makes it possible to minimize the number of the parts to be stockedand maximize a production capacity.

6) It also provides convenience in maintenance service required when the product is damaged, broken or lost, which happens in the field from time to time.
