Suitable for various media and wide selection of materials. Comply with EN593, ISO 5752, BS5155 and AWWA C504 standards, working pressure is 10bar, 16bar or 25bar, made of ductile iron. Installation: Verify that the Ductile Iron Butterfly valve size, pressure rating, and material compatibility match the system requirements. Inspect the valve and ensure that the sealing surfaces are clean and free from defects. Install the valve between properly aligned flanges, with the disc in a slightly open position to avoid damage to the sealing surfaces. Apply gasket material, if required, between the valve and flanges, ensuring a tight seal. Secure the flanges using the appropriate bolt and nut combination, tightening bolts in a star pattern for even pressure distribution.

The OS&Y stem is most popular, but Non-Rising Stem type is also in our scope. Both flexible and Solid disc are available. For big size or Big pressure valve, By-pass design is optional.Below seal gate valve also falls in our ability. A gate valve, known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance. The size of the open flow path generally varies in a nonlinear manner as the gate is moved. This means that the flow rate does not change evenly with stem travel. CAST STEEL GATE VALVE-DIN is usually for working condition in which the valve is not opened or closed frequently, and supports gate fully open or fully closed. It’s not suitable for adjustment or throttling. Gate valve includes three types-Wedge gate, Knife Gate and Parallel Gate. The disc of Wedge gate valve comes with Solid Type and Flexible Type. Flexible Wedge Gate Valves design consists of two independent and flexible wedge halves, that allow a relative movement to accommodate changes in the body seat angles. Solid wedge is designed in one-piece model while flexible wedge offers a wedge shape for both seats.

Valve Size:  DN25 – DN1000  Pressure Rating: PN10 Material: Ductile Iron(GGG50),Aluminum, WCB and Stainless Steel Operation: Manual, Pneumatic and Electric; Ends Dimension:DIN2533 BS4504,JIS B2212,ANSI B16.5 Test & Inspection: EN12266, API 598 Leflow’s high quality Pinch Valve is the ideal solution for shutting off and controlling abrasive, corrosive and fibrous media such as emulsions, silt, dust,gaseous substances, compressed air, powdery materials and particles. It has following options: 1.Body can be made of Ductile Iron, WCB,Aluminium and other Stainless Steel; 2.Operation can be Manual, Pneumatic and Electric; 3.Sleeve can be made of EPDM,NBR,NR(Natural Rubber) and so on. Pinch valve, also known as pressure valve,is a valve that uses manual, pneumatic, electric and other driving methods to squeeze the internal rubber tube to On-off or regulate the flow. Pich valve is composed of upper and lower valve body, rubber sleeve, Upper and lower stem, upper and lower gate, left and right guide post and other parts; As the core component, the rubber sleeve is usually composed of an inner layer, an outer layer and a reinforcing fiber, and is formed by vulcanized rubber. Common rubber sleeve materials are natural rubber, fluorine rubber, neoprene rubber ball, EPDM rubber, nitrile rubber, food grade rubber ball and so on. When the hand wheel is rotated clockwise, the size of the pinch valve stem simultaneously drives the upper and lower valve plates to compress the rubber sleeve, and the valve is closed. When it is turned anti-clockwise, the valve is opened due to the joint action of the elasticity of the rubber sleeve and the pressure of the medium. The gate moves up and down between the left and right guide to complete the valve opening and closing; During the closing, Once it feels the connection between upper and lower sleeve, then stop continuing to close, More torque will damage the sleeve. The Pinch valve can be installed in any direction on the pipe, and there is no medium flow limit. After using for a long time, if the rubber sleeve is found to be worn and leak happens, just disassemble the upper and lower valve body and replace it with a new rubber sleeve. The valve body can be reused and the maintenance cost is very low. Manual Pinch Valve Leflow’s Manual Pinch Valve is a reliable, low-maintenance, and cost- effective valve designed for challenging slurry, abrasive, and corrosive chemical applications across various industries. The 100% full bore design eliminates any dead points or gaps, seats, or bearings where slurries might stagnate and affect operation, or even lead to valve failure. The manual pinch valve features a bi-directional drip-tight closing function, and its design meets face-to-face dimensions identical to gate valves, plug valves, and ball valves (DN25 – DN1000). They are designed with flange connections conforming to EN12266, API 598 standards, or DIN2533 BS4504, JIS B2212, ANSI B16.5.

Name: Double eccentric butterfly valve Another name: High performance butterfly valve Applicable: Water plant, power plant, steel plant smelting, chemical industry Features: Longer life and good stability Features: Leflow is providing high quality Double-offset butterfly valve. We produce double eccentric butterfly valves with diameters ranging from DN100 to DN1200. Double offset uses two separate offsets to achieve a bubble-tight. One of the offsets is the location of the valve shaft relative to the centerline of the bore. Another offset is between the centerline of the disc/seat sealing surface and the shaft. This structure make the valve has following benefits: 1. Double Eccentric structure ensures low operating torques with zero leakage performance; 2. Inner and outer surfaces of the valve are coated with fusion bonded epoxy,and Its thickness can be adjustable; 3. Low moments are obtained by decreasing the friction through self-lubricating bushings; 4. Can bear high stretching stresses on the pipeline through the ductile iron body and disc; 5. High impact resistance. 6. Pressure loss is at minimum level by double shaft design. 7. Sealing gaskets fasten by bolt can be replaced at field condition; 8.
