FAQ

Q1: What is the maximum working temperature?

For this model, the operating temperature depends on the seat material. PTFE offers a range of -20°C to 180°C, while EPDM is suitable for -40°C to 120°C. Please verify with our engineers for specific conditions.

Q2: Can this valve be used for abrasive slurry?

Yes, the knife gate design is particularly effective for slurries with solid particles. The WCB body provides good wear resistance.

Q3: What is the lead time for production?

Typically 30-45 days after confirmation of order, depending on quantity and specifications. Please contact our sales team for exact delivery schedules.

Q4: Do you provide certification for pressure testing?

Each valve is tested according to API 598 standards, and test reports are available upon request.

Q5: Can I get a sample for testing?

Yes, samples can be provided. Please contact us to discuss sample fees and logistics.

Q6: What are the available end connections?

Typical connections include wafer, lug, and flanged. Flange standards can be customized (ANSI, DIN, etc.) based on project requirements.

Q7: Does the valve support electric actuation?

Yes, we can fit electric, pneumatic, or hydraulic actuators as per your control system requirements.

Q8: Is on-site installation support available?

We provide technical guidance and drawings for installation. For complex projects, we may offer on-site supervision, subject to negotiation.
