PTFE Seat Wafer Type Butterfly Valve
PTFE Lining Valve also known as fluorine plastic lined corrosion resistant valves, are fluorine plastic molded into the inner wall of the steel or iron valve bearing parts or the outer surface of the valve inner parts. Fluorine plastics here mainly include: PTFE, PFA, FEP and others. FEP lined butterfly, teflon coated butterfly valve and FEP lined butterfly valve are usually used in strong corrosive media.

Replacable Seat Aluminum Hand Lever Wafer Butterfly Valve with EPDM Seat
Replaceable seat is soft seat, Replaceable valve seat, when the valve seat is damaged, only the valve seat can be replaced, and the valve body can be kept, which is more economical. The aluminum handle is corrosion-resistant and has a good anti-corrosion effect, The seat EPDM can be replace by NBR, PTFE, Choose according to the customer’s medium.

Worm Gear Operated Wafer Type Butterfly Valves
The worm gear is suitable for large butterfly valves. The worm gearbox usually uses for sizes big than DN250, there are still two-stage and three-stage turbine boxes.
-
Worm Gear Wafer Butterfly Valve
Worm gear wafer butterfly valve, usually used in size big than DN250, The worm gear box can increase the torque, but it will slow down the switching speed. Worm gear butterfly valve can be self-locking and will not reverse drive. For this Soft seat worm gear wafer butterfly valve, the advantage of this product is that the seat can be replaced, which is favored by customers. and compared to the hard back seat, its sealing performance is superior.

Worm Gear Wafer Butterfly Valve with Nylon Covered Disc
The nylon disc butterfly valve and nylon plate have good anti-corrosion and epoxy coating is used on the surface of the plate, it has very good anti-corrosion and wear resistance. The use of nylon plates as butterfly valve plates allows butterfly valves to be used in more than just simple non-corrosive environments, broadening the scope of the use of butterfly valves.

Brass Bronze Wafer Butterfly Valve
Brass wafer butterfly valves, usually used in the marine industry, good corrosion resistance, usually are aluminum bronze body, aluminum bronze valve plate. ZFA valve has ship valve experience, to Singapore, Malaysia and other countries have supplied ship valve.
-
PTFE Full Lined Wafer Butterfly Valve
Fully lined butterfly valve, with good anti-corrosion performance, from the structural point of view, there are two halves and one type on the market, usually lined with materials PTFE, and PFA, which can be used in the more corrosive media, with long service life.
-
Electric Actuator Flange Type Butterfly Valves
The function of the electric butterfly valve is to be used as a cut-off valve, a control valve and a check valve in the pipeline system. It is also suitable for some occasions that require flow regulation. It is an important execution unit in the field of industrial automation control.
-
Flange Butterfly Valve with Supporting Legs
Usually when the nominal size of the valve is greater than DN1000, our valves come with support legs, which makes it easier to place the valve in a more stable way. Large diameter butterfly valves are usually used in large diameter pipelines long with you over to control the opening and closing of fluids, such as hydroelectric power stations, hydraulic stations, etc.
-
NBR Seat Flange Butterfly Valve
NBR has good oil resistance, usually if the medium is oil, we will preferably choose NBR material as the seat of the butterfly valve, of course, his medium temperature should be controlled between -30℃~100℃, and the pressure should not be higher than PN25.
-
PN16 CL150 Pressure Flange Type Butterfly Valves
The Flange centerline butterfly valve, can be used for pipeline flange type PN16, Class150 pipeline, ball iron body, hanging rubber seat, can reach 0 leakages, and is a very should welcome butterfly valve. The maximum size of the midline flange butterfly valve can be DN3000, commonly used in water supply and drainage, HVAC systems, and hydropower station systems.
-
PTFE Seat Flange Type Butterfly Valve
PTFE’s acid and alkali resistance is relatively good, when the ductile iron body with PTFE seat, with stainless steel plate, butterfly valve can be applied in the medium with acid and alkali performance, this configuration of the butterfly valve broadens the use of the valve.
