Cast Steel Check Valves

Non SlamCheck Valve Nozzle Bolted 300lb Pipline Valve EDVC No-slam check valves are silent in-line and specifically designed to automatically protect critical components from reverse flow as well as pressure transients. Fast and prompt closing is assured due to the powerful spring and short valve stroke. As forward velocity begins to slow, the spring assist starts to close the disc. By the time it reaches zero, the valve disc is closed against the seat before reverse flow can

SWING CHECK NON-RETURN VALVES EDVC swing check valve is suitable for various operating conditions of pipeline for petroleum, chemical, pharmaceutical, chemical fertilizer and electric power industry. Swing check valve is suitable for clean medium like water, oil, steam, acid medium, and not suitable for medium with solid particles and great viscosity. EDVC Swing Check/Non-Return Valves are designed and manufactured as per BS1868. Check Valves are widely essential in the

300LB LCC Bolted Bonnet Piston Check Valve A piston check valve is essentially a lift check valve. It has a dash-pot consisting of a piston and cylinder that provides a cushioning effect during operation. Because of the similarity in design to lift check valves, the flow characteristics through a piston check valve are essentially the same as through a lift check valve. The valve's top-entry design allows for easy access and replacement of all valve internal parts with

300LB CF8M Wafer Tilting Disc Check Valve CF8M Wafer Tilting Disc Check Valves are designed and manufactured strictly to International Standards API 6D, ASME B16.34 or Equivalent, to reduce the flow resistance and pressure drop to the minimum possible extend with a feature of compact structure & Low emission service. Characteristics: The characteristics for the valve type are: Short face-to-face length - invaluable where the space is limited. Low weight results in low

API594 Stainless Steel 900LB Lug type Dual Disc Check Valve Dual-plate check valves offer a unique compact design with high performance. The special retainerless body and the quick acting spring provide a fast response to flow reversal, minimize the stress and prolong the service life. The valve is designed with two discs hinged at their sides like a door, eliminating the effect of gravity. Consequently, very little energy is needed to open the valve and maintain this

DIN F4 GS-C25 Non Return Lift Check valve Lift check valves are significantly custom-made for high-pressure service wherever speed of flow is high. In lift check valves, the piston disc is accurately target-hunting by long contact and an in depth sliding work with the peerless targeted dash pot. The walls of the piston and dash pot are of roughly equal thickness. Giant steam jackets are placed outside of the dash pot and within the piston to eliminate sticking out due to

300LB CF3M Non-Slam Nozzle Check Valve EDVC No-slam check valves are silent in-line and specifically designed to automatically protect critical components from reverse flow as well as pressure transients. Fast and prompt closing is assured due to the powerful spring and short valve stroke. As forward velocity begins to slow, the spring assist starts to close the disc. By the time it reaches zero, the valve disc is closed against the seat before reverse flow can occur,

API Cast Steel Wafer Dual Disc Check Valve Wafer check valves are available in many sizes, typically from 2” to 24”, support customize bigger size. Body styles include wafer, lug, double flanged and extended body. Wafer check configurations are available in retainer-less style, wafer, extended body wafer and lined. Typical body materials are cast iron, ductile iron, WCB cast steel, 316 stainless steel and other alloys. Common seating materials are EPDM and Viton. Design

Axial Flow Check Valve EDVC axial flow check valve is a streamlined venturi port design and available in size from 2" to 48" and in pressure rating from ASME class 150 through 2500 and a wide range of body and trim materials for special application requirement. Axial flow check valve, the disc is the only moving part to minimize internal wear, and the configuration of disc, seating and body provides streamlined flow path with a venture effect so as to reduce pressure loss as

Tilting Disc Check Valve is a new valve that designed and developed by the combination of many years of our company's valves production technology and aboard advanced product. Its main advantage is to overcome the impact and water hammer phenomenon caused by the swing check valve, lift the back valve in the operating conditions, to achieve no impact operation. Specifications • product design according to: ASME B16.34

2500LB CF8M Pressure seal swing check valve The pressure seal valves are designed in accordance with BS1868 and ASME B16.34 for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service. It is an

Bolted Bonnet Full Opening Swing Check Valve EDVC Full Port Swing Check Valves are all designed to operate without any assistance, reacting to dominate flow direction. Minimal forward flow will instantly open the valve disc, while zero flow closes the valve disc preventing backflow. Optional mechanical devices (manual levers or gear operators) are available to manually or remotely open or close the valve. The full port design results in lower turbulence and pressure drops

ANSI Cast Steel 300LB Swing Check Valve EDVC swing check valve is suitable for various operating conditions of pipeline for petroleum, chemical, pharmaceutical, chemical fertilizer and electric power industry. Swing check valve is suitable for clean medium like water, oil, steam, acid medium, and not suitable for medium with solid particles and great viscosity. Swing Check Valve Design Features Design standard as per: BS1868,ASME B16.34, GB/T 12236. Compact and reasonable
