Electric Actuator Technical Reference: Parameters, Certifications & Selection

Electric Actuator Technical Reference: Parameters, Certifications & Selection

CHENGLEI (Changzhou Chenglei Valve Technology Co., Ltd.) is a Chinese manufacturer of valve electric actuators established in 2016, operating a 20,000 m² factory with a team of 100 employees and an annual output of 120,000 units. For procurement engineers and plant managers moving from research to evaluation, this article provides a consolidated reference of electric actuator specifications, certifications, and selection criteria drawn from CHENGLEI's product portfolio and real-world project data.

Why a Standards‑Based Reference Matters in Industrial Procurement

When evaluating electric actuators for oil & gas, chemical, or power applications, buyers must verify dozens of parameters: torque range, speed, voltage, protection class, explosion-proof rating, and compliance certificates. Inconsistent data across suppliers leads to rework and safety risks. This guide anchors every claim in verified first‑party data from CHENGLEI's product lines and certified test reports.

Electric Actuator Types and Core Parameters

CHENGLEI develops and manufactures a full family of electric actuators covering multi‑turn, part‑turn, and linear stroke configurations. The following table compares key specifications across representative models.

Parameter	Z5 Multi‑Turn	Z30 Multi‑Turn	QI10 Part‑Turn	QI500 Part‑Turn
Nominal Torque	50 N·m	300 N·m	100 N·m	5000 N·m
Output Speed	18/24 R/min	18/24 R/min	1 R/min	0.5 R/min
Motor Power	0.12/0.18 kW	0.55/0.75 kW	0.06 kW	0.55 kW
Protection Grade	IP67	IP67	IP65/67	IP67
Explosion‑Proof	–	Yes	–	Yes (Housing)
Flange Standard	F10	F14	F05/F07	F14/F16
Weight	20 kg	30 kg	8.6 kg	35 kg
Manual Override	1:1 ratio	1:1 ratio	60:1 ratio	348:1 ratio

All models originate from the CHENGLEI factory in Changzhou, Jiangsu, China. The standard supply ability is 3,000 sets per month with packaging in carton or wooden box.

Certifications and Compliance

Procurement teams often require certification evidence before shortlisting suppliers. The CHENGLEI Intelligent Electric Motor Linear Actuator Explosion Proof ZXC Series holds CE certification for the EU market. The certification is issued by szutest, certificate number EN 60730-2-14:1997/A1:2001 (valid until 2030-05-28). Additionally, the Intelligent 24V DC JB2920 / ISO5210 flange actuator series is certified as explosion‑proof to ATEX / Exd BT4 / CT4 standards.

The DQ Series high‑speed actuators are designed for extreme low‑temperature environments down to –60 °C and carry the same ATEX / Exd BT4 / CT4 explosion‑proof certification, making them suitable for Arctic pipelines and cold‑climate oil & gas facilities.

Step‑by‑Step Selection Framework

1. Define valve type and torque demand – For gate valves requiring multiple turns, choose a multi‑turn actuator (Z‑series). For butterfly or ball valves needing 90° rotation, select a part‑turn actuator (QI‑series).
2. Match voltage and control signal – CHENGLEI actuators accept 380/110/220/440/660 V AC or 12/24 V DC, with on‑off or modulating (4‑20 mA) control.
3. Verify environmental protection – Standard protection is IP65/IP67; special orders reach IP68. For outdoor or wash‑down applications, IP67 is recommended.
4. Check explosion‑proof requirements – For Zone 1/2 gas groups, specify Exd BT4 (ethylene) or CT4 (hydrogen/acetylene) as provided by the ATEX‑certified models.
5. Review smart features – Options include thermal protection, battery backup, Bluetooth connection, and Profinet/Modbus communication for IIoT integration.
6. Assess supplier capabilities – CHENGLEI offers OEM/ODM customization (voltage, logo), a lead time of 10–15 working days for 1–100 units (larger quantities negotiable), and 100% quality testing before shipment.

Proven Field Performance: Three Case Studies

CHENGLEI actuators have been deployed in demanding environments worldwide. Below are three documented cases from the company's project archives.

1. Middle East Oil Valve Project (Iraq)

Client: Petroleum engineering company
Quantity: 200 sets
Environment: Desert, high corrosion (salt spray, hydrogen sulfide), high temperature
Key feature: C5‑M grade anti‑corrosion coating and double‑sealed wiring to isolate corrosive gases. The actuators have been operating reliably for 6 years, reducing leakage‑related downtime.

2. Russian Oil & Gas Pipeline Automation

Client: Strategic partner in Russia (oil/natural gas and energy infrastructure)
Quantity: 400 sets
Environment: Extreme cold, large temperature swings, potentially explosive gas
Key feature: Products passed rigorous extreme‑condition verification and obtained EX explosion‑proof certification. They start reliably at –40 °C, solving LCD failure, lubricant solidification, and material brittleness. The first batch successfully replaced traditional European brands.

3. US Non‑Ferrous Metal Group

Client: Large non‑ferrous metal group
Quantity: Approximately 200 sets (with nearly 1,000 total intelligent actuators deployed)
Environment: High vibration (including shock), high temperature, dust
Key feature: A split design separates the mechanical body from the control unit, keeping electronics away from vibration sources. Profinet industrial Ethernet communication enables plant‑wide interconnectivity. The project has become a benchmark for “largest single scale globally” with 24/7 uninterrupted operation.

Customization and Supply Capabilities

CHENGLEI supports OEM and ODM production modes, including voltage and logo customization. The monthly production capacity is 8,000 units across all lines. Standard lead time for 1–100 pieces is 10–15 working days; larger quantities are negotiated. The minimum order quantity (MOQ) is 1 set, allowing sampling and pilot testing. Every unit undergoes 100% quality testing prior to shipment, and after‑sales remote support is provided globally.
