对于任何氢氟酸阀门，短时排放是影响阀门性能的关键因素。我们承诺我们的阀门在减少排放方面的指标优于行业标准，而且为我们的用户提供优质产品的历史已有50多年。Velan能够提供具有下列优点的全系列Philips认证和UOP认证的API
600氢氟酸闸阀、截止阀和止回阀。
Fugitive emissions are a critical factor in the
performance of any HF Acid valve and at Velan, we have been committed
to reducing emissions beyond the industry standards, and providing the
highest quality products to our customers for over 50 years. Velan offers
a comprehensive line of Phillips approved and UOP listed API 600 gate,
globe and check HF acid valves with several benefits.
结构特征：
DESIGN FEATURES:
- 在阀杆孔内的后座上镀镍，可应用在严酷的烃化环境。
Nickel plated overlay on backseat in stem hole
to combat severe alkylation conditions.
- 用于保证阀门完整性的氢氟酸检测漆。
HF acid detecting paint to ensure valve integrity.
- 阀杆 - 由实心时效硬化的K-Monel 500材料制造，强度更强，耐腐蚀性能更好。
Stem - made from solid age hardened K-Monel 500
for increased strength and corrosion resistance.
- 铸件结构
符合B16.34相关标准的X射线“RT”品质的铸件。
Velan是世界上最先采用MAGMASOFT®计算机铸件模拟仿真程序来保证高品质的阀门制造商之一。
Casting design
X-ray “RT“ quality castings as per B16.34 acceptance standards.
Velan is one of the first valve manufacturers to have the MAGMASOFT®
computer casting simulation program to ensure high quality levels.
- 阀帽连接 - 精密机加工，使用寿命更长。
Bonnet Joint - accurately machined for better
service life.
- Monel密封焊接阀座
在Monel阀座后和周围进行焊接安装，以确保零泄漏。焊接后，采用现代先进的技术进行研磨抛光，以防止应用过程中被腐蚀。
Seal Welded Seats in Monel
Monel seats are welded-in for ensuring zero leakage behind and around
the seat and then ground and lapped after welding using state of the
art technology to prevent in-service corrosion.
- 阀体/阀帽壁厚符合API 600标准。
Body/Bonnet wall thickness to API 600.
- Velan的低短时排放保证建立在广泛的实验室测试和现场经验基础上。
