Overview
SUC is a leader in the R&D and manufacturing of valves in the field of fluid control, and is particularly good at solutions for switch valves in harsh working conditions. The ball valves it designs and manufactures have many invention patents, and the safety and reliability of its products have been successfully tested in the market. SUC "ball valve provides powerful performance and diversified structural design. Its design, manufacturing, testing, quality, etc. fully meet domestic and international standards such as GB, API, ASME, ISO, etc. It is one of the most trusted valves in the petrochemical, coal chemical, polysilicon, silicone, mining and other industries. SUC always implements the concept of safety, efficiency and controllability, and is committed to independent innovation in green technology. Each valve can meet the safety integrity level (SIL2/SIL3) and meet the customer's TSO needs. Every detail of the product fully reflects the ingenious design of safety: automatic pressure relief function of the middle cavity, anti-static design, fireproof design, valve stem anti-blowout design, etc.

1. F series floating soft seal ball valve

Features and advantages

1 Concise switch indication

- The valve stem head indication is consistent with the ball flow channel

- Effectively avoid the operator's switch misjudgment

2 Drive connection and locking function

The valve body and drive connection flange meet ISO 5211 standard

The manual ball valve has locking anti-shock and anti-misoperation functions

3 Unique elastic seat design

- The valve seat has the characteristics of wear resistance and automatic compensation
- Low opening torque, long service life, good sealing performance

Eliminate cold flow and meet high and low pressure alternating working conditions

4 Low fugitive packing structure

- The packing structure meets the low fugitive requirements

Meet the requirements of ISO15848A/B grade and TA-LUFT

5 Anti-blowout and anti-static valve stem

- An anti-static structure is designed between the ball, valve stem and valve body
- The valve stem is designed as an anti-blowout structure

6 Assembly without adjustment design

- The left and right body connections are quantitatively compressed, and the metal surface contacts after assembly, and no adjustment is required

Assembly and maintenance are very simple, with 100% interchangeability

7 Fireproof design in accordance with API607/API6FA

- The valve has fireproof function and meets the requirements of API607/API6FA
