Key features

High Flow Capacity: Flow capacity is 20-25% larger than single-seat valves of the same diameter.

Large Pressure Difference: Unbalanced forces offset each other, allowing operation under large pressure differences.

Multiple Material Options: Body available in Carbon Steel (WCB) and Stainless Steel (304, 316, 316L).

Versatile Actuator Models: ZHA/B multi-spring diaphragm actuators with various active areas and strokes.

High Adjustment Accuracy: Features simple connection and reliable performance for precise control.

Comprehensive Certifications: Certified with GS, CE, and ISO9001 standards.

Dual Seat Design: Double seats provide strong flow capacity but result in higher leakage.

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.

Product Q&A

Q:What is the difference between double-seat and single-seat valves?

Double-seat valves can withstand larger pressure differences and have higher flow capacity, but they have larger leakage. Single-seat valves have smaller leakage but can only withstand small pressure differences.

Q:Is this valve suitable for high viscosity media?

No, due to the complex flow path and serious erosion/cavitation damage at high pressure differences, it is not suitable for high viscosity or fiber media.

Q:What materials are available for the valve body?

The body material options include Carbon Steel (WCB) and Stainless Steel (304, 316, 316L).

Q:What is the nominal pressure range?

The nominal pressure options are PN16, PN40, and PN64MPa.

Q:What are the available actuator models?

Available models include ZHA/B-11, ZHA/B-22, ZHA/B-23, ZHA/B-34, ZHA/B-45, and ZHA/B-56.
