Quality Assurance (QA):
Every step from procurement through production, welding, assembly, testing, and packaging is in accordance with quality programs and procedures (ASME Section III manual and ISO 9001 manual).
Quality Control (QC):
The QC is responsible for all aspects of quality, from receiving of material to control of machining, welding, nondestructive examination, assembly, pressure testing, cleaning, painting, and packaging.
Pressure Testing:
Each valve is pressure tested in accordance with API 6D, API 598, or special customers' requirements as applicable.
Design Features
(1) Double "D" stem head which ensures handle lever will always be mounted correctly, parallel to flow, indicating valve open and closed positions. (2) Secure line flow locking device: the valve is equipped with an integral locking device to secure line flow. (3) Anti-static device: Spring loaded pins assures that the electrical continuity between the ball, stem and body, to avoid arcing due to static buildup. (4) Blow-out proof stem: the lower end of the separate stem is T-shoulder shaped to create an integral collar making the stem blow-out proof. (5) Bolted body maintains seal integrity with properly torqued bolting. (6) Fire safe design: metal to metal sealing shuts off valve flow when soft sealing materials are destroyed by fire.
