About
The VACCO V1E10689-01 is a ½” low-pressure bi-directional latch valve that employs VACCO’s proven torque tube technology. It features an all-titanium construction for light weight, ensuring compatibility with stainless steel systems through transition tubing. This valve is fully flight-qualified and has extensive heritage, designed for high reliability, tight leakage, and quick response. It includes two integral microswitches and a 100-micron absolute inlet/outlet filter. This model is identical to the V1E10691 except for lower back pressure relief. Performance characteristics are based upon customer requirements.
