Fluorine plastic polymer FEP (F46) lined ball valves for petroleum, chemical, dyestuff, pesticide and other industries in a variety of strong corrosive medium developed for open and close control. F46 fluorine plastics have excellent resistance to corrosive media. Is currently the best anti-corrosion material. F46 fluorine plastic lined valves, shell casting with precision casting, smooth appearance, strength increased. Department contacts with the corrosive medium with fluorine plastic liner bag and the appearance of multi-functional combination of metal, so products in a variety of acids, bases, salts, corrosion of medium strength good work. Seals used by the Shanghai Institute of Organic patent - fluorine plastic alloy, which changes the creep F46 seals to further enhance the service life of the product, the product was -50 degrees -150 degrees to ensure the long-term use within the with open and close rapidly, flow resistance, etc, would you get a satisfactory economic results.

We are a professional valve manufacturer with many years experience, good quality and best price.
The valve disc is rubber-packed to get excellent sealing effect by the rubbers resilient deformation.Non-rising resilient seated gate valve solves the problem in general gate valve such as leakage,rusting etc. and saves installation space.It is widely used in tap water in dustry,sewage treatment,shipping,construction,petroleum,chemicals,food,pharmacy,textile,electric power,metallurgy and energy systems pipeline to adjust and shut off fluid. air control valve has lift,stop,drop of control handle switch .the valve still has self-locking
function. Air control valve has lifting, stopping, dropping of control handle and power take-off controlling switch. The valve also cooperate with the air-controlled reversing valve to achieve the dump truck's lifting ,stopping and dropping . Otherwise, the check valve may control the power take-off. when the valve in the process of dropping.the power take-off controlling switch can automatically return to the position. Material:WCB, CF8M, CF3M
Design & Manufacture Std.:ASME B16.34 Face to Face Std.: As Per Manufacturer s Standard China Strainer is necessary equipment for pipeline systems, generally installed in the entrance of pressure-relief valve, pressure-release valve, water-positioner valve or other equipments, to protect the valves and equipments by clearing the impurity in medium. This strainer has feather of advanced structure, little resistance, efficient pollution-discharging, can be used in water, oil and gas, and generally mesh amount is 18~30 for water passing, 40~480 for gas passing, customization will be accepted. FEATURES
Cost effective - No external power required - Simple installation - Light weight - Flushing port - Flanged connection The pump protection valve is intended and manufactured to provide against excessive fluid temperature rise within the pump housing. Low flow conditions can cause, cavitation, vibration, bearing failure, damage to mechanical seals and pump housing. The Pump Protection Valve uses the simplest design, a compacted helical spring with a seat and seal arrangement to seal the valve. As pressure in the pump builds up past the pump manufacturers designed pressure specification, the seal is pushed upward off the seat, allowing the fluid or steam to discharge through the bypass line of the valve.As the pressure decreases and regulates itself back to its regular levels, the seal will reseal itself into its seat, guarding the china plug valve against damage and even explosion. We have got the ISO9001 quality certification systemand ISO14000 environmental authentication system. We collaborate with Shanghai scientific research units, Beijing senior professional factory technical, owns advanced laboratory testing means. Automatic pump recirculation valve body's materials is stainless steel , such as 304, 316, 316l, etc. We can produce according to you sample or your drawing. We can also so OEM. Our price is competitive and the delivery time is strict. It is according to your quantity, usually within a month. We also provide pump fittings, furnace fittings and some other precision casting. Welcome new and old customers to contact us for cooperation!

Information:china ball valve and china safety valve The choke valve, a main component of Christmastree, is design to control production rate of the oil well,with working pressure up to 10000psi. Choke valvescan be classified as follows: adjustable choke valves and positive choke valves. By rotating handwheel todrive the stem, the adjustable choke valve is designedto adjust the effective area available for the flow to ac-complish control of production rate. The positive chokevalve is design to accomplish control of production rateby changing flow beans.
China choke valve are mainly used for flow and pressure adjustment in HP pipelines. We provide two types of choke valves: fixed and adjustable. The adjustable choke valves can be divided into needle, plunger and orifice plate type. They can be manually or hydraulically operated, and conform to API 6A and 16C. Flow and pressure can be adjusted through changing fluid passage section by cone surface of needle type valve bar, vertical movement of plunger or rotation of orifice plate. We can provide fixed or adjustable choke valves with sizes of 2"&3" and pressures of 5000-15000psi(35-105Mpa).
