Polytec’s Most Representative Product – PE Ball Valve
PE ball valve of Polytec has wide range of products that are in service for various applications. The applications include natural gas distribution systems, coal bed methane, industrial plants, water distribution systems and wastewater & sewage systems.
Polytec Polyethylene (PE) ball valve is mainly used as a flow control fitting in low pressure gas distribution network. It opens/closes the gas flow at the time of emergency, maintenance and piping replacement.
As the PE ball valve is built with plastic, it has longer lifespan than steel valves. Also, the plastic body is free from erosion caused by chemical substances in the gas or electrical contact (LPG, LNG and other gas fuels). Full bore design and smooth PE wall allow the maximum flow capacity for the gas transportation.
PE Ball Valve’s integral purge connection makes it easy for compact and cost-effective installation. Massive designed body is also resistant to all piping loads, both in mechanical and thermal load. Specially compounded seats show excellent elasticity and toughness over the valves’ entire life.
Polytec PE ball valve also shows good performance in water and chemical application due to no erosion by chemical and water and good flow capacity by lower friction coefficient than steel valves. It is easy to install with wide range of product size (20-400 mm, 1/2~16 inches). Lastly, it is environmentally friendly material as Polyethylene is safe for the human body.

own technologies. It has been continuously growing up to become the best company in the field. Now, as a specialist of total ballast system line up, all of its staff s are going to operate faster with 3B in their mind.
Hanla IMS has developed the eco-friendly EcoGuardian™ system for treating aquatic invasive species in a ship’s ballast water. Treatment method is side-stream type which enables the system to be remotely installed, away from the ballast line. The EcoGuardian™ system can be installed separately by unit, so relocation of other equipment and additional engineering can be minimized.
precision mild steel, copper, stainless steel and other materials for tubes. The machine is basically composed of six to ten rolls. The exclusive processing of thin-wall tubes is possible by customers’ requests.
KTM Tech was founded as Karam Machinery in 1990. The company designed a four-roll type of square tube mill in Korea in 1991. The company designed NC straightening machines in 2008. In 2013, the company took part in the KOMAF 2013 as an exhibitor. On December 5, 2014, KTM Tech established its R&D institute. The company spares no efforts to develop and produce better machines.
The KCG series cage-guided control valves are designed for high performance to exceed the limits of other conventional valves. With numerous trim configurations (including low-noise and anti-cavitation) and its ability to handle large pressuredrops, the KCG series can be applied in a variety of severe services. They feature various body materials such stainless, cast steel, high alloy steel and various trim materials such as hardened trim, stellite and others. They also have reduced port area and microflow control trim.
The KBV 300/400 series smart segmental ball is an eccentric plug, high performance rotary control valve. Designed for use in a wide variety of applications ranging from low pressure, high “CV” to slurry and pulp services, to oil and gas services. The smart segmental ball can handle shut-off pressure drop up to 50 bar. Operating temperatures can be from -50 degrees to 450 degrees. The smart segmental ball control valves consist of a straight valve body with less flow resistance and separable plug with flow guid that rotates eccentric.
With accumulated experiences and production knowhow, the company is currently supplying a variety of items ranging from auxiliary products for heavy electrical machinery to general industrial products.
Among the maker’s hottest-selling items are LED traffic safety arrows. CE-approved, the product (WS-02) is easy to use and ideal for preventing secondary car accidents. It can be used as an arrow indicator light and helps users to indirectly control the traffic flow. Equipped with powerful neodymium magnet, it can be easily mounted in various locations on a car.
The firm’s other popular items include gas insulated switchgear (GIS)-transporting covers. Made of plastic resin, the products eff ectively solve the problems of ordinary steel products. Very light, they allow the user to conduct the installation work by himself, thus helping save time and labor costs.
minimize the loss of lives. Unlike ordinary products which have just one hole for gas injection on top, they have an additional hole for measuring gas pressure, thus preventing explosion.
Among the hagship prosucts from the company are: hydraulic breaker / hammer & spare parts, hydraulic vibrating ripper, non-hydraulic ripper, hydraulic vibrating hammer, hydraulic bucket crusher, hydraulic tilting bucket, hydraulic quick coupler, hydraulic plate compactor, hydraulic drum cutter, hydraulic crusher, hydraulic grab / grapple, hydraulic super long reach boom, high reach demolition, material handler, telescopic dipper, and front shovel.
projects in chemical plants, petrochemical and thermal plants, and oilfi eld and refi nery applications, both onshore and off shore. It is capable of providing timely technical solutions to meet customers’ specifi c applications and needs and will promptly att end to any urgent enquiry. With its long-standing experience and in-depth engineering knowledge in valve manufacturing, it is committ ed to satisfying its customers in terms of quality, price, and delivery and after sales service.
Trunnion ball valves are blow-out proof and antistatic, using spring and small ball design, the ball and body from static bore stem. The static caused by the ball and seat friction are grounded to avoid fi re or explosion. The stem incorporates the blow-out proof design. The stem and body have excellent sealing performance with redundant steam seals and a graphite gasket on the gland plate. They also have cavity relief design and double lock and bleed. The two seats in the trunnion mounted ball valve can isolate the inlet and outlet to implement the double block. When the valve is closed, with both ends having pressure, the cavity and the bore can be blocked. The media in the cavity can be bled down by the operation using a pressure relieving device.
condition of high-temperature and high-pressure that is impossible to ues by Tefl on Touch Ball Valve. And there is no leakage because seat is pressed to ball bydisc spring regularly all the time. Excellent roundness of ball by using lapping machine is developed to improve seal capacity. Also, surface of the valve is harder than common ball valves. This valve shows good effi ciency especially in separate line because there is no galling on surface by special treatment.
are the easiest way to join and repair pipes of all materials.
Youngnam Metal has 30 years of experience in manufacturing stainless and plastic pipe couplings & pipe repair clamp joints. Its technical capacity in this field has been highly evaluated by many customers and other parties concerned, not only for comprehensive applications but also for a significant reduction in expenses.
significantly lower prices. The company exports 80% of its products to foreign countries.


Hi-Clamp has two types of series, the KY series and the GY series. As for the KY series, there are a movable type in which the press bolster or the slide moves along the T-slot and a fixed type of the flange type. Since the cylinder part and lever part are separated, a uniform force is applied on the T-slot shape and measure. GY series are similar to KY series in terms of structure. However, since the surface of the cylinder makes contact with the die, the clamping force is high.
