What is the leakage rate standard?

EPDM seals offer zero leakage; metal-to-metal seals have a leakage rate of less than KV 10-5.

What accessories can be equipped?

Accessories include positioners, solenoid valves, air filters, pressure reducers, travel switches, and handwheels.

Key features

High Sealing Performance: Utilizes PTFE and elastic materials for zero leakage with EPDM and superior sealing under pressure.

Long Service Life: Features thrust bearings and self-lubricating PTFE to reduce friction and ensure smooth, long-term operation.

Fail-Safe Operation: Single-acting actuators automatically open or close upon power failure based on control system requirements.

Wide Application Range: Suitable for chemical, petroleum, food, and pharmaceutical industries; handles gas, liquid, steam, and sewage.

Versatile Actuator Options: Supports single/double action types with accessories like solenoid valves, limit switches, and positioners.

Low Fluid Resistance: Straight-through design ensures minimal flow resistance and large output torque for efficient switching.

Durable Material Construction: Available in WCB, 304, 316, and 316L stainless steel bodies with nitriding treated stems for corrosion resistance.

Flexible Connection Types: Offers flange, weld, and thread connection forms to suit various industrial piping systems.

AI-Powered supplier vetting

SummaryZhitai Technology Group Co., Ltd. is a China-based manufacturer of pneumatic actuators and industrial valves, operating from Zhejiang with 61 employees. It holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications. The supplier demonstrates broad customization, 3D design, ODM, and OEM capabilities, supported by two R&D engineers and documented design review, verification, and validation records. It has procedures for complaints, corrective and preventive actions, finished-product inspection, and supplier-service assessment. Production-related evidence includes inventory capability, valid contracts with associated subcontractors, and a one-month average lead time in both peak and off-season. Limitations include no stated quality assurance in quality-control processes, no new products launched in the previous year, no SDK, no overseas warehouse or showroom, and no Fortune 500 customer collaboration. Financial credibility cannot be determined from the non-financial information provided.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and a limited company located in Zhejiang, China. Its listed products include pneumatic actuators, control valves, and multiple valve types, indicating direct industrial product manufacturing rather than a purely trading or service business.

CertificationsThe supplier holds ISO9001:2015, ISO45001:2018, and ISO14001 management-system certificates. These certifications provide explicit evidence of certified quality, occupational health and safety, and environmental management systems.

After-Sales capabilityThe supplier has documented and followed procedures for customer complaints and corrective/preventive actions, while its technology engineers provide technical support for production and after-sales service. However, the slices do not quantify response times, service coverage, or resolution performance.

R&D capabilityThe supplier provides 3D software design, ODM, and multiple customization services, with two R&D engineers and auditable design input, output, review, verification, and validation documentation. Nevertheless, it reported no new products in the previous year and has no available SDK, so the evidence supports design execution but not strong recent product innovation.

Production capacityProduction-support evidence includes uniform finished-product inspection instructions, inventory capability, valid manufacturing contracts with associated subcontractors, written supplier-service assessment procedures, and a one-month average lead time in both peak and off-season. However, the supplier explicitly reports no quality assurance in its quality-control processes, which is a stated deficiency in production quality capability.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, and also provides 3D software design, ODM, and OEM services. This combination indicates broad customization coverage across design and manufacturing requirements.
