SOV high-tonnage double-acting hydraulic cylinders are specifically designed for heavy lifting applications, capable of handling up to 1,000 tons. These cylinders feature an integral stop ring that provides protection against piston blow-out, ensuring safety during operation. The double-acting design allows for positive retraction, making them ideal for precise and controlled movements. The cylinders have a baked enamel exterior finish and plated pistons, which offer superior resistance to corrosion, enhancing their durability in harsh environments. A safety valve on the retract side helps prevent damage in case of accidental over-pressurization, adding an extra layer of protection. Interchangeable, hardened grooved saddles are standard, allowing for easy maintenance and replacement. A plunger wiper is included to reduce contamination, extending the life of the cylinder.

Models above 150 tons are also available with standard stroke lengths of 100, 200, and 250 mm. Company Information Shanghai SOV Hydraulic Technology Co., Ltd is a manufacturer specializing in the design and production of hydraulic cylinders (capacities from 10 to 1000 tons), synchronous PLC hydraulic systems, hydraulic jacks, torque wrenches, and related components. Since its establishment in 1995, the company has evolved from being an OEM supplier for Enerpac and Titan to developing its own brand, SOV. The factory is CE and ISO9001:2008 certified. Clients Our clients include major Chinese industrial companies such as China Petroleum, Baosteel, Sinopec, China State Grid, Jiangnan Shipyards, Sany Group, and China Railway Construction Corporation. Our synchronous PLC hydraulic system played a significant role in the development of China's high-speed rail network. In 2011, our sales revenue reached $30 million, establishing us as one of the leading manufacturers in the Chinese hydraulic cylinders market, particularly in the field of ultra-high pressure hydraulic cylinders for industrial and construction applications. Main Products We produce a wide range of tools including: • Hydraulic cylinders and jacks (5–3000 ton), single and double acting, hollow plunger, low height, ultra-pressure, lock nut • Hydraulic torque wrenches, electric torque wrenches, and pneumatic torque wrenches (100–160,000 Nm) • Hydraulic bolt tensioners (M24–M600), hydraulic pullers • Hydraulic pumps (manual and electric type, up to 4000 bar) • Integrated hydraulic lifting systems (4–99 points for house translation or leveling, bridge support, tank welding support) • Hydraulic nuts and couplings (M50–Tr1000), hydraulic hoses These products are widely used in industries such as steel plants, cement, chemical, refinery, bridges, and railway construction and maintenance. Why Choose SOV? Q1: What is the brand name of your products? A: Our own brand "SOV". We are a Germany-owned factory. OEM is available upon request. Q2: Do your hydraulic cylinders suffer internal leakage? A: There are three main reasons for internal leakage: overload, poor polishing control, and faulty seal kits. Vehicles in China often operate under overload conditions, so our cylinders are designed to withstand this. We use CNC machines for precision polishing and imported seals to meet customer requirements. Q3: Is your piston rod prone to breaking? A: We use hard chrome-plated quenched and tempered 45# steel for the piston rod, ensuring sufficient hardness and toughness. Q4: Is your design reasonable? What about the safety factor of your product? A: Our R&D team has extensive experience in design. We also collaborate with universities for research and education. You can rest assured. Q5: What is the delivery time? A: With over 1000 sets of advanced equipment, we can fulfill large orders quickly. Generally, it takes 7–20 days. Q6: What after-sales service do you provide? A: If the quality does not meet your expectations, we will cover all losses and provide technical support to resolve any issues.
