Casting Iron Body CF8 Disc Lug Type Butterfly Valve
A lug type butterfly valve refers to the way the valve is connected to the piping system. In a lug type valve, the valve has lugs (projections) that are used to bolt the valve in between flanges. This design allows for easy installation and removal of the valve.

Hand Lever Actuated Ductile Iron Lug Type Butterfly Valves
Hand lever is one of manual actuator, it usual used for small size butterfly valve from size DN50-DN250. Ductile iron lug type butterfly valve with hand lever is a common and cheap configuration. It is widely used in different conditions. We have three different kinds of hand lever for our clients to choose:stamping handle,marble handle and aluminium handle.Stamping hand lever is the cheapest. And we usually used marble handle.

Ductile Iron SS304 Disc Lug Type Butterfly Valves
Ductile Iron body,SS304 disc butterfly valve is suitable for weakly corrosive medium. And always applied to weak acids, bases and water and steam. The advantage of SS304 for disc is that have a long service life, reducing the times of repairs and lowering operating costs. Small size lug type butterfly valve can choose hand lever, from DN300 to DN1200, we can choose worm gear.

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.

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.
-
DN1200 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.

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.

Double Flanged Triple Offset Butterfly Valve
The triple eccentric butterfly valve is a product invented as a modification of the midline butterfly valve and double eccentric butterfly valve, and although his sealing surface is METAL, zero leakage can be achieved. Also because of the hard seat, the triple eccentric butterfly valve can withstand high temperatures and pressures. The maximum temperature can reach 425°C. The maximum pressure can be up to 64 bar.

DI CI SS304 SS316 Butterfly Valve Body
The valve body is the most basic, one of the most important parts of the valve, choose the right material for the valve body is very important. We ZFA Valve has many different model of valve body to meet your require. For valve body, according to the medium, we can choose Cast Iron, Ductile Iron, and we also have stainless steel valve body, such SS304,SS316. Cast iron can be used for media that are not corrosive. And SS303 and SS316 weak acids and alkaline media can be selected from SS304 and SS316.The price of stainless steel is higher that cast iron.
