About Carter Valve
Nearly 50 Years
Engineering-Driven Sealing Reliability
Carter (Hangzhou) Valve Manufacturing Co., Ltd.
Our company is an engineering-led valve manufacturer based in Zhejiang,China. We build valves and actuator systems for industrial users who care about one measurable outcome: dependable isolation over long operating cycles.
Our development approach connects design geometry, sealing contact behaviour, torque stability, and verification testing—so performance can be validated in real working conditions, not just described on paper.
What We Offer
Valve Platforms
From high-performance butterfly valve and multi-offset designs to metal-to-metal seated isolation platforms, we provide configurations for both standard duty and severe-service conditions.
Actuation & Control Integration
We deliver actuator and control integration for critical isolation and regulated operation—supporting commissioning, tuning, and lifecycle maintainability.
Application Engineering Support
Selection support based on media, temperature/pressure envelope, solids/corrosion risk, shutoff class targets, and maintenance realities—so the chosen valve matches the duty, not just the datasheet.
Service
We supply industrial valve solutions—covering butterfly valve platforms and related isolation valves—manufactured to major international standards (ANSI, API, DIN, BS, JIS, and China GB) as well as customer-specific requirements. Our products support a wide range of applications across oil & gas, refining, chemical processing, LNG, power generation, and pipeline transportation.
The members of the Carter Valve team are rigorous about product reliability and quality
Because performance must be proven in real working conditions. For this reason, as a manufacturer of valves, our missions are:
Duty-Based Selection
Match valve design, seat type, and actuation to the real service conditions—temperature, pressure, media, and cycle life.
Standards & Compliance
Build to globally recognised standards and documented customer specifications, with clear acceptance criteria.
Verified Quality
Apply disciplined manufacturing and inspection so sealing performance is repeatable, not accidental.
Lifecycle Support
Support commissioning, maintenance planning, and spares strategy to protect long-term uptime.
A Platform Built Around Sealing Reliability
Carter Valve’s six-eccentric butterfly valve technology is built to address common leakage and wear patterns through geometry and controlled sealing contact. The goal is straightforward: stable shutoff performance, predictable operating torque, and reduced sealing degradation over time.
Instead of relying on a single “stronger seal” claim, we focus on how the sealing interface behaves across real cycles—start/stop frequency, temperature swings, pressure variation, and maintenance intervals.
Quality Is a Lifecycle Discipline
Advanced designs only create value when manufacturing and inspection consistently reproduce the intent. That’s why our quality approach covers the entire lifecycle—from configuration control and process discipline to inspection methods and verification testing.
We focus on what plant operators care about: repeatable shutoff performance, consistent torque behaviour, and dependable service life under the specified duty conditions.
R&D and Testing Capability That Supports Validation
We maintain dedicated R&D and testing resources to support development verification and application validation—helping ensure that valve performance targets are supported by test logic, not assumptions.
