  • General Valve

    The range of Valves was developed to provide a cost effective, reliable and

    easily maintained control valve capable of working in rigorous environments.

    The quick change trim option provides for easily accessible seat and trim

    components to minimise fitting and parts replacement times.

    Stem guided contoured trim in both balanced and non balanced configuration

    gives excellent rigidity and resistance to vibration and service wear.

    The valve is designed to accommodate other products within the Dong Yang

  • Diaphragm Valve

    The Diaphragm valve structures with 3 major parts(Body, Diaphragm, and Bonnet).

    The mechanical structure of this valve is so simple that the complete isolation of fluid from the metal parts of valve body and trim. The diaphragm valve is mainly used in Chemical Plant using lot of corrosive liquids.

    These Diaphragm valve may be used for weir, angle and straightway styles. and Diaphragm valve be classified body or non-lining type.

    PFA Lined Diaphragm Valves

    The range of applicable fluid is very pure water for semi-conductor production to

    the sticky and contaminated sewage, from corrosive liquid with many contaminants to gas.

    Because as such a flexibility of valve configuration can keep the inside of the valve extremely clean with PTFE or PFA (Non-Elastic Fluoropolymer), the diaphragm valve is used as the key component in the process line requiring high pure gas, liquid and water line in semi-conductor plant and pharmaceutical industry.


    *The price is lower than steel valve due to material can be selected in consideration of fluid, and chemical proof inside of valve.

    *Economical costs of installation and spare part.

    *With change of parts, the goods can be used as a new one, and the Life style would be a long

    *Since the fluid can be adjusted, it can be used as a control valve

    Complete the block leakage is possible

    *Structure of contacting between non-ferrous, it can be blocked the leakage completely

    *With no stuffing box structure, blocking 100% of leakaging of vacuum pressure

    Efficient structure

    *It has body and cover without dead space

    *Since the cover is seperatable, fluid is contacting with diaphragm and Iining fluid can be protected it form contaminate stuffing box, therefore it is suitable for semiconductor medicine, food and beverage and GMP process

    Excellent structure for flowing of fluid

    *Due to less contect between the parts and flowing tube the bic and Cv is high

    *With pocketless structure, flowing fluid is smooth

    *With fluid chanal is streamline, the resist is less, and structure of working of resistance, it can keep manual flowing of fluid

    *Due to straight type in which the direction of fluid is close to straight, loss of pressure and gethering of fluide is small

    Diaphragm Valve for biotechnology

    Dongyang F&C Co., Ltd. is a manufacturer and Exporter of fine quality products for the Biotechnology, Pharmaceutical &fermentation manufacturing industries. we specialize in products used for sterile fluid processing in cell culture and protein purification.

    Due to the diaphragm Valve’s streamlined flow path, absence of cavities and minimal contact surfaces, the valve is considered the “cleanest” valve or the valve least likely to cause contamination.

    *Lining Description

    -lining materials and methods.

    The choice of lining materials and the method of lining are critical

    We begin with the purest fluorocarbon materials.

    To assure lining integrity and maximum corrosion resistance, Tufline uses only PFA and FEP fluorocarbon.


    PFA is the standard lining material for all Tufine Lined Accessories.

    PFA is a fluoropolymer with extended temperature limits.

    It is a copolymer that combines the carbon-fluorin with a perfluoroalkoxy side chain

    PFA offers a variety of attributes and benefits.

    ·Handles a wide range of fluids

    ·Chemically inert

    ·Heat resistant

    ·Weather resistant

    ·Stress-cracking resistant

    ·Negligible moisture adsorption

    ·Better sealing and wear resistance between parts-because it is moldable and machinable to close tolerances.

    ·PFA is a true thermoplastic and is melt processible, so it can be locked to the valve components.

    Blow-out or liner collapse are virtually impossible.


    As an option, the Tufline 45˚ Lined Ball Check Valve and the

    Sight Flow lndicator are availble with a fluorinated ethylene(FEP)lining

    FEP offers benefits similar to those of PFA. The primary difference is the pressure/temperature ratings.

    PFA can be used in higher temperature applications than FEP.

    -Locked-in linings.

    Tufline Lined Accessories have cast dovetail recesses and machined groowes that lock the lining to the body casting.

    Blow-out or liner collapse are virtually impossible.
