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

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.

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.

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

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.

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.   Product Parameter Size Range: 2" - 8" (50mm - 200mm) Body Style: Double Flanged Temperature Range: -20°C to 150°C) Pressure Ratings: Bidirectional Bubble-tight Shutoff: to 250 psi (17.2 Bar) Body (CWP): 250 psi (17.2 Bar) Body Materials: Ductile Iron Disc Materials: Ductile Iron Seat Materials: Bonded EPDM Applications: Wastewater, Seawater

PN16 Non Rising Stem Groove Type Gate Valve DN100 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.

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.

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.
