Established in 1992, Shanghai Petro Valves Factory (TOPVAL) is leading manufacturer and Designer. Topval manufactures industrial valves, electric actuators, and hydraulic actuators. The company has a registered capital of 60 millions, a total investment of 80 million RMB, owns a land area of 61000 square meters, one in Shanghai City, One in Xiamen City, One in Luoyang City. The company has a modern manufacture plant, manufacturing processing and testing equipment, strong technical force, has achieved ISO9001:2000 quality system certification, API, CE certification and other international authoritative certification.

After more than 30 years of development, TOPVAL with its excellent product quality and perfect service system, won the majority of users of praise, in the industry establish a good corporate image, brand awareness is increasing after year 2000.

Our company introduced the United States technology development and production of SR/SJ intelligent non-invasive electric actuator is a kind of high performance products, in the technique completely overcomes traditional stroke drift, torque actuator uncertainty, maintenance workload shortcomings. SR series actuators are widely used in electric power, metallurgy, petroleum and natural gas, industrial water, paper, cement, shipbuilding, chemical industry, practice has proved, the SR/SJ series is worthy of trust products.

Our design, production and operation of various types of valves: gate valve, globe valve, ball valve, check valve, butterfly valve, regulating valve, diaphragm valve, exhaust valve, gate, round gate, safety valve, regulating valve and pipe fittings and other 700 kinds of products, more than 8000 specifications. Materials are cast iron, cast steel, stainless steel, heat-resistant steel, low temperature steel, nominal pressure 1.6-65Mpa, 150Lb-4500Lb, temperature -196 ℃ -650 ℃, specifications range 3-4000mm. Mainly used in electric power, petroleum, chemical industry (coal chemical industry), metallurgy, coal, city water supply and drainage, sewage treatment, water engineering, ship, heating, medical and metallurgical industries.

Product design: each product design and development are to go through market research, and product design review at each stage, technology review. All use of CAD computer-aided design, so as to shorten the product development cycle, ensure the high quality of product design.

Valve casting production: the production line of cupola and resin sand casting, supply 6000 tons. Can effectively overcome the ordinary clay sand casting porosity, poor dimensional stability of internal defects of trachoma. In order to guarantee the product appearance and intrinsic quality of each batch of products, our company production casting demanding physical, chemical analysis, all cast trimming all adopt mechanical impact cleaning and sandblasting treatment and surface paint or epoxy coating powder processing, ensure the appearance quality of castings.

The product machining: has a CNC machining center, double column vertical lathe, digital floor type boring and milling machine, rotary table (Table 2 * 3M), CNC lathe, vertical lathe, horizontal lathe, radial drilling machine, sawing machine, vertical milling machine, a face plate (no grade), horizontal boring machine and boring machine, milling machine, planer and dozens of set of high precision equipment to ensure that the product processing precision.

Inspect and test products: Inspection and testing of TOPVAL products in strict accordance with the ISO9001 quality assurance system and the relevant national standards, products in the production of every process organic processing workers, assembly of specific markers of workers and inspection personnel. Each link can be traced back, each valve regardless of size, must by Taiwan sealing test before leaving the factory, and the assembly, inspection personnel marker and issuance of certificate of product and label party is permitted to leave the factory.

Products after sale service: advocate "advanced service" "full service", in product quality, delivery date, technical services, training, compensation for breach of contract, service hotline, price from 7 aspects such as implementation of commitments.

Company an excellent sales network covering 31 provinces and autonomous regions. products are widely used in national large-scale key projects. In addition, products are exported to foreign countries. Parts production and assembly of localized, so that the TOPVAL can provide the required products for domestic users in the shortest possible time.
