Worm Gear Ductile Iron Resilient Seated Butterfly Valve
Worm Gear Ductile Iron Resilient Seated Butterfly Valve
Butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates. This Resilient Seated Butterfly Valve is double flanged design which can be used for dead-end service.
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.

Ductile Iron Y Type Strainer
Ductile Iron Y Type Strainer
This product is designed for remove foreign matter from pipe lines and provides protection for pumps, meters, valves, and other similar mechanical equipment, which is called as Strainer. "Y" Type Strainers are named after their shape and normally used for course filtration. But with large filtration area can be used with fine mesh also.
The Strainer improves the clearance in the medium, and prolongs the life of valves; protect expensive pumps, meters and other equipments.
A Y-strainer can be installed in either a horizontal or vertical position (Downward flow) with the screen elementpointing downward. This allows the strainer screen to collect material in the strainer at the lowest point of the screen.

Ductile Iron Flange Silent Check Valve
Ductile Iron Flange Silent Check Valve
Silent Check Valves are designed to prevent water hammer in multi-story buildings and for use in vertical turbine pump installations when pumping from a well to an elevated reservoir. Silent Check Valves are recommended for commercial and industrial HVAC applications such as heating systems and condensate return lines. The valve closes silently, is low in cost, reliable and requires no regular maintenance. When the pump stops, the spring forces disc closed against slight pump head at zero velocity which results in silent closure.

One Way Non Return Swing Check Valve
One Way Non Return Swing Check Valve
Rubber disc check valve is mainly composed of body, cover and rubber disc three parts.Rubber disc is made by steel plate, steel bar and the reinforced nylon fabric substrate.This valve is usually installed in the outlet of the pump or inlet of water pool to prevent the water backflow and avoid damages to the pump caused by the water hammer phenomenon.
The water flow in water supply or irritation networks often starts or stops abruptly causing hydraulic hammer shock, the main factor for breakage and damages of the pumps and pipes. The check valve with the rubber blocking eliminates the pump and network destruction risks because it receives and absorbs all the created high pressure functioning like the shock absorber of an automobile. The rubber disc check valve is designed to provide the best possible protection to pump installations and water networks.
Advantages:
Absorbs part of the hydraulic surge waves
Silent operation
Smooth liquid flow
Little maintenance required
Applications:
Irrigation
Water supply networks
Pump stations

Water Pressure Relief Valve for Fire Fighting
Water Pressure Relief Valve for Fire Fighting
This valve is used for the high building fore-fighting system,To prevent the pipeline and equipment damage due to overpressure.
The body uses full passage streamline design, of a small fluid resistance and a heavy flow. This valve can be used as either a pressure releasing or holding valve. when used as the former, it can release the pressure surpassing the safe value set with the pilot valve and keep the pressure inside of the pipeline below the safe value to prevent system against danger due to an excessively high water pressure;while used as the latter,it can keep the upstream water supply pressure of the main valve over some set value,this is because water supply to the downstream can not be done,unless the upstream is higher than the set value,in order to make sure of he upstream water supply pressure of the main valve.

Water Pressure Release Valve for Fire Fighting
Water Pressure Release Valve for Fire Fighting
The valve consists of the main valve and outside installed control pilot valve, mainly installed in the bypass of the protected water supply system in the building, guarantee the pressure of the main valve upstream water supply zone, when the pressure in the water supply pipe exceeds the pressure set by the pressure releasing valve, the pressure releasing valve is switched on to prevent pipeline and equipment from damage by pressure exceeding. This valve is mainly used in pressure releasing of the fire test circulation system in high-rise buildings, is the upgrade replacement product of the spring safety valve.
Features:
1)Reasonable and novel structure, reasonable use of the hydraulic principle to control.
2)Long service life.
3)Valve clack quick opening and slow closure, no water hammer impacting.
4)High sensitivity, safe pressure discharge.
5)Stable operation, no noise.

Pre-action Systems Fire Alarm Check Valve
Pre-action Systems Fire Alarm Check Valve
Pre-action sprinkler systems are specialized for use in locations where accidental activation is especially undesirable, such as in museums with rare art works, manuscripts, or books; and data centers, for protection of computer equipment from accidental water discharge.
Pre-action systems are hybrids of wet, dry, and deluge systems, depending on the exact system goal.

Wet Pipe System Fire Alarm Check Valve
Wet Pipe System Fire Alarm Check Valve
The alarm check valve is a water flow alarm device designed for vertical installation in the main supply to a wet pipe sprinkler system. When a flow of water from the system equals or exceeds that of a single sprinkler, the valve is to actuate a fire alarm.

Ductile Iron Water Seal Thread Gate Valve PN16
Ductile Iron Water Seal Thread Gate Valve PN16
A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. The gate faces can be parallel but are most commonly wedge-shaped (in order to be able to apply pressure on the sealing surface).
Gate valves are used to shut off the flow of liquids rather than for flow regulation. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance.
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
