Product Description
Key Features & Technical Advantages
🧼
Each valve should be cleaned by ultra-sonic cleaning machine, in case of contaminant left inside, guarantee the cleaning of the valve, in case of pollution to the pipeline.
🏷️
Marker Plate located on body side of the valve, easy to watch after installation. Material of the plate is SS304, with laser marking. We use stainless steel rivet to fix it, makes it cleaning and tighting.
⚙️
Non-pin stem design adopt anti-blowout structure, the valve stem adopt double jump ring, not only can compensate the error in installation, but also can stop the stem being blow off.
🛡️
The valve adopt epoxy powder painting process, thickness of tht powder is 250um at least. Valve body should be heating 3 hours under 200℃, powder should be solidify for 2 hours under 180℃.
⚡
Pneumatic actuator adopt double piston structure, with high precision and effective, and stable output torque.
🧪
Special Test: According to customer’s requirement, we can do any test you need.
✅
ZFA Valve strictly execute API598 standard, we do both side pressure testing for all the valve 100%, guarantee deliver 100% quality valves to our customers.
🏭

Frequently Asked Questions (FAQ)
What testing standards are followed before valves are delivered?
ZFA Valve strictly executes the API598 standard, conducting 100% two-sided pressure testing for all valves. Additionally, specialized testing can be performed based on specific customer requirements.
How is the valve stem secured to ensure operational safety?
The non-pin stem features an anti-blowout structure with a double jump ring. This design compensates for installation discrepancies and reliably prevents the stem from blowing out under pressure.
What coating process is applied to protect the valve body?
The valves undergo an electrostatic epoxy powder painting process with a minimum thickness of 250 µm. The valve body is preheated for 3 hours at 200°C, followed by powder solidification for 2 hours at 180°C to guarantee maximum durability.
What actuator and operation options are supported?
Valves can be fitted with hand levers, gearboxes, electric actuators, or double-piston pneumatic actuators with stable output torque, depending on operational demands. Standard ISO 5211 top flanges are utilized for actuator mounting.
How does ZFA Valve maintain clean internal valve surfaces?
Every valve is cleaned thoroughly using an ultrasonic cleaning machine to remove contaminants, preventing pipeline pollution and guaranteeing smooth downstream operation.
What size ranges and pressure ratings are available?
Sizes range from DN40 to DN1200 with pressure ratings including PN10, PN16, CL150, JIS 5K, and JIS 10K, accommodating multiple connection standards such as API, BS, DIN, and ISO.
