Features 特征

Machined from solid steel barstock for durability.
The series employs a threaded sleeve locking
mechanism, mates with matching male threads on
the nipple. The two halves must be manually threaded
together for connection.
Hard, chrome alloy balls are used for valving, It be
loaded on the valve seat by the springs.
The valve provides a metal-to-metal seal between the
ball and coined seat.
The interface seal is polyurethane which resists high
pressure extrusion.
A threaded valve retainer provides a valve stop that
assures positive valve alignment.
Compatible with PARKER 3000 Series, FASTER PVVM
Series.
