Overview
At HSH Valve, quality, compliance, and engineering reliability are the foundation of our global valve supply capability. We specialize in Electrical On/Off Valves and Electrical Control Valves designed for industrial automation, process control, and critical engineering applications.
Our valves are widely applied in EPC projects, industrial plants, and infrastructure systems across water treatment, HVAC, power generation, chemical processing, and automation industries.
We focus on delivering verifiable compliance, engineering-grade quality assurance, and long-term operational reliability for global procurement and engineering teams.
Quality Management System
Our manufacturing system is built on an ISO 9001:2015-certified quality framework with full process control and engineering traceability.
Key controlled systems include:
Documented Engineering SOPs for all production stages
Supplier qualification and audit system
Incoming Quality Control (IQC) with material verification
In-Process Quality Control (IPQC) at critical manufacturing steps
Final Quality Control (FQC) with functional validation
Corrective and Preventive Action (CAPA) system for continuous improvement
Each valve is produced under a repeatable, controlled, and traceable manufacturing system, suitable for industrial-grade applications.
Certifications & Compliance Verification
HSH Valve products comply with international industrial standards required for global EPC and engineering procurement projects.
Available compliance frameworks include:
ISO 9001:2015 Quality Management System (Certificate available)
CE Marking (PED 2014/68/EU Pressure Equipment Directive)
RoHS compliance for electrical components
API design compatibility (API 6D / API 608 depending on project requirements)
ATEX explosion-proof solutions for hazardous environments (optional)
SIL safety integrity design support for control applications (optional)
Compliance Proof & Documentation
For engineering procurement, we provide:
Certificate copies (ISO / CE / others upon request)
Inspection reports from third-party organizations (SGS / TUV / BV if required)
Project-specific compliance documentation for tender approval
Factory audit support for EPC qualification
Material Traceability System
We implement a full material traceability system to ensure engineering safety and quality accountability.
Key features:
- Certified raw material sourcing system
- Incoming material verification including PMI testing (optional)
- Heat number (batch number) tracking for all pressure parts
- Digital traceability linking raw material → Machining → Assembly → Finished valve
- Material Test Certificates (MTC) issued for each shipment
This system ensures every valve can be fully traced back to its original material batch.
Engineering Manufacturing Control
Our manufacturing process is designed for industrial reliability, precision, and long-term operational stability.
Key engineering controls
CNC precision machining with dimensional inspection reports
Torque-controlled assembly for electric actuators
Controlled assembly environment for sealing and pressure components
Critical process verification at each manufacturing stage
Functional consistency inspection for batch production
Engineering focus
Stable actuator torque output
Reliable sealing performance under pressure
Consistency across batch production
Testing & Validation System
Each valve undergoes 100% testing before shipment to ensure safety and performance under real operating conditions.
Standard test procedures:
- Hydrostatic pressure strength test
- Pneumatic leakage test
- Seat sealing performance test
- Electrical actuator function and cycle test
- Endurance cycling test (optional for projects)
- High/low temperature performance testing (optional)
- Project-specific engineering test requirements
Test documentation:
All test results are recorded and can be provided for:
- Project approval
- EPC technical review
- Third-party inspection
Quality Assurance & Third-Party Inspection
We implement a multi-layer quality assurance system designed for industrial procurement and EPC project requirements.
Quality control stages:
Incoming Quality Control (IQC)
In-Process Quality Control (IPQC)
Final Quality Control (FQC)
Pre-Shipment Inspection (PSI)
Third-party inspection (SGS / TÜV / BV or customer-appointed inspectors)
We fully support independent inspection for engineering procurement validation.
Documentation for EPC & Engineering Projects
We provide complete engineering documentation packages for EPC contractors, distributors, and industrial procurement teams.
Available documents:
Material Test Certificates (MTC)
Pressure test reports
CE / ISO compliance certificates
Technical datasheets (engineering-grade)
GA drawings and installation drawings
Operation & Maintenance manuals (IOM)
Project-specific documentation upon request
All documents can be customized for tender and project approval processes.
Global Engineering Quality Commitment
HSH Valve is committed to becoming a reliable global valve supplier for industrial automation and EPC engineering projects.
We continuously improve:
Manufacturing precision
Quality control systems
Engineering compliance capability
Documentation accuracy
Our goal is to provide long-term, stable, and verifiable valve solutions for global engineering procurement teams.
