Company Information
Shanghai SOV Hydraulic Technology Co., Ltd is a manufacturer specializing in the design and production of hydraulic cylinders (capacity ranges from 10 to 1000 tons), synchronous PLC hydraulic systems, hydraulic jacks, hydraulic torque wrenches, electric torque wrenches, and hydraulic components.
Certificate
Since its establishment in 1995, Shanghai SOV has successfully transitioned from being an OEM manufacturer for Enerpac and Titan to creating its own brand, SOV. Our factory has been continuously certified by CE and ISO9001:2008.
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 has played a significant role in the construction of China's high-speed rail network. In 2011, our sales revenue reached 30 million USD, making us one of the leading manufacturers in the Chinese hydraulic cylinders market, especially in the field of ultra-high pressure hydraulic cylinders for industrial and construction applications.
Main Products
We are a manufacturer of various 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 types (up to 4000 bar)
• Integrated hydraulic lifting systems (4–99 point lifting systems for house translation or leveling, bridge support, and tank welding support)
• Hydraulic nuts and couplings (M50–Tr1000), hydraulic hoses
Our products are widely used in industries such as steel plants, cement, chemical, and refinery sectors, as well as in bridge and railway construction and maintenance.
Why Choose SOV?
Q1: What is the brand name of your products?
A: We have our own brand "SOV." We are a German-owned factory. OEM is also available upon request.
Q2: Does your hydraulic cylinder suffer from internal leakage?
A: There are three main causes of internal leakage: overload, poor polishing, and inferior seals. As is well known, vehicles in China are often overloaded, so our products are designed to withstand such loads. We use CNC machines to ensure precise polishing and import high-quality seals to meet customer requirements.
Q3: Is the piston rod prone to breaking?
A: The piston rod is made of hard chrome-plated quenched and tempered 45# steel, ensuring sufficient hardness and toughness.
Q4: Is your design reasonable? What about the safety coefficient of your product?
A: We have a strong R&D team with extensive experience in design. We also collaborate with universities for research and development. You can rest assured.
Q5: What is the delivery time?
A: With over 1000 advanced machines, we can meet large orders in a short time. Typically, it takes 7–20 days.
Q6: What kind of after-sales service do you provide?
A: If the product quality doesn't meet your expectations, we will compensate for all losses and offer technical support to solve any issues you may face.
