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.

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.   Product Parameter   DN D D1 NO.×NXφ L H(Close) H(Open) 40 150 110 4×18 178 322 374 50 165 125 4×18 178 322 374 65 185 145 4×18 190 332 395 80 200 160 8×18 203 350 429 100 220 180 8×18 229 420 524 125 250 210 8×18 254 581 721 150 285 240 8×22 267 581 736 200 340 295 12×22 292 736 942 250 405 355 12×26 325 880 1013 300 460 410 12×26 356 1009 1117 350 520 470 16×26 385 1300 1655 400 580 525 16×30 406 1380 1805 450 640 585 20×30 432     500 725 650 20×33 457     600 840 770 20×36 508    

Manual Operated Ductile Iron 4 Inch Butterfly Valve DN200 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.   Product Parameter Model A C D ZSXF-50-D(G) 90 55 60.3 ZSXF-65-D(G) 90 65 76.1 ZSXF-80-D(G) 100 70 88.9 ZSXF-100-D(G) 110 87 114.3 ZSXF-125-D(G) 110 100 139.7 ZSXF-150-D(G) 110 115 165.1 ZSXF-200-D(G) 134 150 219.1

Manual Operated Ductile Iron Signal Fire Valve Butterfly 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.   Product Parameter Model A B C D ZSXF-50-D(G) 90 205 55 60.3 ZSXF-65-D(G) 90 220 65 76.1 ZSXF-80-D(G) 100 220 70 88.9 ZSXF-100-D(G) 110 269 87 114.3 ZSXF-125-D(G) 110 280 100 139.7 ZSXF-150-D(G) 110 295 115 165.1 ZSXF-200-D(G) 134 352 150 219.1
