TRIMEC Industrial Piston Valves

Innovative TRIMEC Piston Valves for Dust and Gas Cleaning Systems

The Italian engineering company TRIMEC has established itself as a leading developer and manufacturer of highly efficient low-pressure piston valves. These valves are critically important for pulse-jet regeneration systems of bag filters used in industrial aspiration. In addition to shut-off valves, TRIMEC's product portfolio includes air receivers and intelligent control units. This allows EV Group China to offer comprehensive solutions for modernizing dust and gas cleaning installations. TRIMEC products are widely used in markets across Europe, Latin America, and Asia, confirming their global recognition and reliability.

The TRIMEC piston valve functions as a precision pulse-jet unit, ensuring instantaneous delivery of compressed air into the injector system. The acoustic wave generated effectively removes settled dust from the surface of the filter bag. Optimizing the technology for low-pressure operation significantly reduces energy consumption for compressor equipment, which is critically important for industrial enterprises. This equipment is in demand in the cement, metallurgical, and glass industries, as well as in thermal waste treatment plants.

Key Design Features and Operating Principle:

• The piston mechanism, equipped with precision guides and wear-resistant seals, guarantees durability and reliability.
• The valve body has an optimized straight-through path, minimizing pressure losses and increasing efficiency.
• The control chamber ensures rapid actuation, which is critical for pulse systems.
• The high-speed kinematics of the valve ensure an opening/closing cycle time of less than 40 ms, allowing for the formation of a powerful pulse.

The valve's effectiveness is demonstrated by its ability to generate a powerful pulse capable of cleaning filter elements up to 12 meters long by creating stable pressure peaks along the entire length of the bag.

Advantages of TRIMEC Technological Solutions

1. Efficient operation in the low-pressure range (2–4 bar) while maintaining a high pulse amplitude, which significantly saves energy resources.
2. Ultra-fast valve actuation dynamics ensure instantaneous system response.
3. Uniform cleaning of bags regardless of the degree of dustiness and their geometric parameters, extending the service life of filters.
4. High throughput: one valve can serve up to 28 bags. This allows for optimizing the number of connection points and reducing the costs of system pneumatic piping.
5. Increased overhaul interval and overall service life of filter elements due to reduced mechanical stress during purging.
6. Overall system energy efficiency is achieved through optimized compressed air consumption.

Technical Characteristics of TRIMEC Sizes

Where We Apply It

TRIMEC piston valves are widely used in various industries where effective and reliable cleaning of industrial gases from dust particles is required. They are used in aspiration systems at cement plants for cleaning exhaust gases from cement dust, in metallurgy for filtering emissions from melting furnaces and converters, and in the glass industry for cleaning gases from fiberglass and other abrasive particles. In addition, they are indispensable at waste incineration plants and other thermal waste treatment facilities, where they ensure compliance with environmental standards. These valves are a key element in ensuring stable operation and extending the service life of bag filters, reducing the operating costs of enterprises.

What to Replace With / Analogues

If there is a need to select analogues for TRIMEC piston valves, engineers and purchasers can consider products from other leading manufacturers such as Goyen, ASCO, Mecair, or Norgren. It is important to consider that direct replacement requires a thorough analysis of technical characteristics: operating pressure, throughput, actuation time, control type (pneumatic, electric), and compatibility with the existing control system. Special attention should be paid to the materials of the body and seals, especially when working with aggressive environments or high temperatures. When choosing an analogue, it is also recommended to compare the effectiveness of pulse jet cleaning and energy consumption to avoid reducing the performance of the filtering unit or increasing operating costs. In some cases, adaptation or modification of the system may be required to maintain optimal operation.

What to Clarify with the Supplier

When purchasing TRIMEC piston valves from EV Group China, to ensure maximum efficiency and reliability of supplies, we recommend clarifying the following key aspects: the availability of certificates of conformity to international quality standards (ISO 9001, CE), confirming the origin and quality of the products. It is important to request information on delivery times and storage conditions, especially for large batches. Clarify the possibility of providing technical documentation in English, as well as the availability of service and spare parts, such as repair kits and seals. Additionally, it is useful to inquire about the minimum order quantity and payment terms, as well as the possibility of receiving consultations on integrating the valves into existing aspiration systems and optimizing their operation. EV Group China is ready to provide all necessary information for making an informed decision.
