Solutions for Core User Pain Points

Core Function Modules

Zero-Pressure Difference Operation

Core Capabilities: Direct-acting structure for vacuum/low-pressure use, semi-direct-acting design for high-pressure vacuum hybrid scenarios, fast response time (10-30ms)
Applicable Scenarios: Vacuum packaging, sterile pharmaceutical production, low-pressure pneumatic systems
Core Value: Ensures reliable operation without minimum pressure requirements, reduces system startup delays.

Corrosion-Resistant Customization

Core Capabilities: 316L stainless steel body, food-grade PTFE/FKM seals, customizable valve size and actuation mode
Applicable Scenarios: Chemical processing, lithium battery manufacturing, sterile food production
Core Value: Meets strict hygiene and corrosion standards, eliminates frequent valve replacement costs.

Product Advantages

1. Zero-Pressure Compatibility: Direct-acting and semi-direct-acting valve designs allow operation from 0 to 4.0 MPa, suitable for vacuum and high-pressure hybrid environments. This enables use in diverse industrial scenarios that standard valves cannot accommodate.
2. Hygienic and Corrosion-Resistant Construction: 316L stainless steel body and food-grade PTFE/FKM seals compliant with CIP/SIP requirements. This meets sterile production standards for pharmaceuticals and food processing, reducing maintenance frequency.
3. Tailored Non-Standard Solutions: Customizable valve specifications including size, actuation mode, and material to match unique equipment needs. This eliminates the need for equipment modifications, improving overall system efficiency.

Customer Case Verifications

Average verified results include: 300% extension of service life in corrosive environments, 40% reduction in equipment modification costs for non-standard applications, 80% reduction in unplanned downtime due to valve failures.
Typical cases:
