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. - Thrust bearings reduce frictional resistance and reduce operating torque.   Product Parameter   DN 50 65 80 100 125 150 200 250 300 350 400 D 57 60 76 178 322 114 133 159 219 273 325 377 426 140 165 A1 14.5 14.5 14.5 16 16 16 19 19 19 25 25 BA 9.5 9.5 9.5 9.5 9.5 9.5 13 13 13 13 13 C 2.2 2.2 2.2 2.2 2.2 2.2 2.5 2.5 3.3 3.3 5.5 Z81X     L 145 180 180 180 200 240 275 325 355     H 325 455 455 455   500 620 750 800     D0 180 200 200 200   240 320 320 400    

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    

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    Product Parameter   DN L H H1 W C n-D50 E T F 50 178 233 123 203 125 4-φ19 165 19 3 65 190 233 93 203 145 4-φ19 185 19 3 80 203 270 100 203 160 8-φ19 200 20 3 100 229 322 110 203 180 8-φ19 220 20 3 125 254 355 125 280 210 8-φ19 250 20 3 150 267 401 143 280 240 8-φ19 285 20 3 200 292 516 170 330 295 8-φ23 340 21 3 250 330 638 203 382 355 12-φ23 406 26 3 300 356 717 230 420 410 12-φ28 460 26 4 350 381 844 260 420 470 16-φ28 520 26.5 4 400 406 935 282 420 525 16-φ31 580 28 4

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
