Single Eccentric Disc-Shaft Resilient Seated Fire Butterfly Valve
Single Eccentric Disc-Shaft Resilient Seated Fire Butterfly Valve
Butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates.
Products Features
Operation is similar to that of a ball valve, which allows for quick shut off.
Butterfly valves are generally favored because they cost less than other valve designs, and are lighter weight so they need less support. The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow.

Gear Operated Concentric Wafer Fire Signal Butterfly Valve
Gear Operated Concentric Wafer Fire Signal Butterfly Valve
The signal butterfly valve is one of the important accessories in the pipeline of a fire sprinkler system. Its structure is Groove type. As the control valve of the fire sprinkler system, it has the function of transmitting the valve's opening and closing state to the control department to trace the misoperation and improve the safety of the system.
On top of the valve has a signal device connect with stem directly. Under working condition when the valve is mistakenly closed by 25% (1/4 of full opening), the signal device will output a signal to the fire control center. So that relevant personnel can check the situation in time.
The signal butterfly valve can intuitive, clear and reliable reflect the working status of the pipeline system, so widely used in firefighting systems.
Products Features
1) Small and lightweight, easy to disassemble and repair, and can be installed at any position.
2) The structure is simple and compact, 90° rotation open and close quickly.
3) The operating torque is small, labor-saving and light.
4) Complete sealing, water test leakage is zero.
5) Can be applied to a variety of medium.
6) The flow characteristics tend to be straight and the adjustment performance is good.
7) The number of opening and closing tests is up to 10,000 times, the service life is long.
8) Pipes that use gate valves, check valves (spherical shut-off valves), globe valves, plug valves, hose valves, and diaphragm valves, especially in high-rise building fire protection systems and pipeline systems that require showing the valve switching status. This valve can be a good alternative.

Ductile Iron Non Rising Stem Flange Type Gate Valve
Ductile Iron Non Rising Stem Flange Type Gate Valve
There is no upward movement of the stem in a non-rising stem type. The valve disk is threaded internally. The disc travels along the stem like a nut when the stem is rotated. You can see the image. In this type of valve, stem threads are exposed to the flow medium. Therefore, this design is used where space is limited to allow linear stem movement, and the flow medium does not cause erosion, corrosion, or wear and tear to stem material. This type of valve also known as insider screw valve.
Gate Valve Applications
Gate valves are used in almost all fluid services such as air, fuel gas, feedwater, steam, lube oil, hydrocarbon, and all most any services.
Some special gate valve is used in slurry and powder product also such as knife gate valve
Advantages of Gate Valve
Gate valve provides good pressure drop during operation
Most of the gate valve can be used as bi-directional
They are suitable for high pressure and temperature application and required less maintenance

Ductile Iron 6 Inch Flange OS&Y Gate Valve
Ductile Iron 6 Inch Flange OS&Y Gate Valve
One type of valve commonly used to control water flow to fire sprinkler systems is known as an OS&Y gate valve. OS&Y means “outside stem and yoke” or "outside screw and yoke".
OS&Y gate valves operate by opening and closing via a gate, which lowers into or rises out of the valve. Raising the gate allows water to flow through the valve while lowering the gate cuts off the water flowing through the valve. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.
Products Features
- Precision-machined valve stem, reduces operating torque.
- Non-toxic powder epoxy resin spraying on botn inside and outside of the valve to enhance corrosion resistance and improve water quality.
- The valve plate is covered with rubber both inside and outside to guaranteed good sealing. It has strong connection to avoid fall off after long-term use.
- Thrust bearings reduce frictional resistance and reduce operating torque.

Ductile Iron 4 Inch Groove Type OS&Y Rising Stem Gate Valve
Ductile Iron 4 Inch Groove Type OS&Y Rising Stem Gate Valve
For a rising stem valve, the stem will go up while opening the valve and move down when you close the valve. You can see in the image. In inside screw design, the threaded portion of the stem is in contact with the flow medium and when you open the valve, handwheel rise with the stem. Whereas in the case of outside screw design, the only smooth portion is exposed to the flow medium and stem will rise above the handwheel. This type of valve is also known as OS & Y valve. OS & Y means outside steam and York.
Products Features
- Precision-machined valve stem, reduces operating torque.
- Non-toxic powder epoxy resin spraying on botn inside and outside of the valve to enhance corrosion resistance and improve water quality.
- The valve plate is covered with rubber both inside and outside to guaranteed good sealing. It has strong connection to avoid fall off after long-term use.

8 Inch Flange Type Signal Gate Valve
8 Inch Flange Type Signal Gate Valve
The signal gate valve is mainly used in the pipeline of the fire water system as a function of opening and intercepting the fluid in the pipeline, and converting the opening and closing working state into an electric signal through the signal device. The elastic seat sealing gate valve signal gate valve encapsulating the whole valve disc to generate a deformation compensation effect to achieve a good sealing effect, overcome the general gate valve sealing failure, water leakage, and rust phenomenon, more effective saving installation space.
It's mainly composed by the signal device, valve body, valve cover, disc assembly, stem, stem nut, hand wheel and other components. The annunciator is mainly composed of a transmission gear, a transmission rod and a micro switch.
