With rapidly changing World and business environment, the previous model has to be adapted to the current needs of the people. In this regard, we have made a multi-model complex structure by linking the verified valve&fitting manufacturing factories in Turkey in one hand and offering a consumer friendly environment to our business partners. We call our clients as our partners since we share with them the same destiny in each project we are in. There are numerous valve&fitting manufacturing plants in Turkey acting mainly local and not having the experience in international market and their requirements.At this point, we have made official agreements with 20+ factories in Turkey for exporting their products with “TVN” brand.This is why we call this organization as “Turkish Valve Network”.With this business model, we are offering many significant advantages to your partners worldwide by below mentioned main aspects; Very wide range of products to be supplied from single source Linked factories reach an unbelievable scale of production capacity by synchronization Monitoring each factories price/quality ratio and delivery terms in order to meet the demand of our partners in a most competitive and rapid way. Verified factories enhances reliability Wide range of certification Keeping the pulse of the valve&fitting industry Inspection, expediting and monitoring of production Flexibility in product diversification and customer oriented production Rapid and smart solutions Satisfactory after sales service
TVN V203 Hydraulic Tilting Check Valve is the non-return valve preferred in pipe networks where faster closure is required and water hammer affects needs to be absorbed. Through the counter lever and weight attached to its shaft via the hydraulic piston, ensures a soft open depending on the speed of the flow and maintains reduced closing times when flow stops. With its disc design where the center is shifted in two axis, this leads to a big improvement on decreasing operation torque values, lowering the friction on disc sealing area and extended service life.

TVN V301 Dynamic Triple Function Air Release Valve is a unique valve operating without a float, utilizing the rolling diaphragm principle. This unique structure allows the dynamic valves to discharge air from the water system in a controlled and gradual man- ner, preventing slam and local up-surges. When vacuum occurs, the valves fast reaction will draw in large volumes of air into the water system, impeding down-surges and, consequently, all pressure surges in the line. The valves are normally closed when the line is not operating, thus preventing the infiltration of foreign particles and insects into the water system. Air Release Valve Application Range Water transmission Water distribution Pump suction line Peaks and bottom points Next to by-pass valve Related Products V151 Gate Valve Resilient Seated V106 Butterfly Valve Flanged V251 Dismantling Joint Air Release Valve Product Features Float parts made of polyethylene, increase the corrosion resistance, hence increases service life. The polyethylene floats gives advantage for easier replacement. Ductile iron body increases the resistance against impacts. It is necessary to use air release valves on the peak points of the pipelines, in order to maintain the full flow of the water. If the air vacuum via air release valve is less than the discharged water amount, the pipeline will face the risk of torsion. Fully coated body and bonnet, meets the hygienic requirements of the potable water networks. (WRAS coating optional) Double orifice air release valve is installed on the pipe by a flange, release the air received from its outlet through the orifices located above the float parts. When the air release function is completed, the floats travel upper part with the water force and close the orifice outlet, thus preventing the leakage of water. Flange connections according to EN1092-2/ISO 7005-2. Working pressure range from 0.2 to 16 bar. Hydrostatic test pressure for seat: PN x 1.1 , for shell: PN x 1.5 according to EN 12266-1.
V251 Full Tie-Rod Dismantling Joint is the crucial elements for the installation and dismantling of valves and other fittings on the pipelines. The self-restrained function enables tight sealing and stays fixed on the lines with prolonged times. Without a disman- tling joint offering longitudinal adjustment, it is almost impossible to insert a valve exactly into a pipe section. V251 dismantling joint with full-length threaded tie-rods ensures complete restraint and a leak-free operation. Thanks to this adjustability of the dismantling joint, the valve can be fitted next to the dismantling joint, and the dismantling joint can be to set to the exact length required prior to being securely connected to flanges. Application Range Potable water applications Water treatment and distribution systems Mining industry Shipbuilding and drilling facilities Food and chemical enterprises Oil and gas processes Related Products V151 Gate Valve V106 Double Eccentric Butter fly Valve V202 Tilting Check Valve Full Tie-Rod Dismantling Joint Product Features The heavy model V251 is equipped with 3 flanges, is the perfect solution for all standard and non-standard applications. Larger sizes and higher pressure ratings up to 40 bar are always possible depending on customer requirements. Only high-quality EPDM or NBR qualities for water, drinking water and sewage are used for the gasket. These guarantee a clean seal for years and at the same time the movement of the dismantling joint. It is easy to install and remove thanks to the standard longitudinal adjustability of ± 25 mm and thus offers perfect support during the installation and removal of valves. High-quality FBE coatings protect TVN dismantling joints from long term corrosion. Ductile iron GGG-40/50 body galvanized 8.8 bolts, nuts and washers. The bolts, nuts and washers can be chosen as AISI 304 or AISI 316 stainless steel. Certain types of dismantling joints are also suitable for use without restraint in flexible pipelines The ductile iron body has high resistance to the high tension stress which can occur at the pipelines.
