Low Flow Regulators

jrseries

Low flow valves offered in this section are Globe Style regulators, primarily bar stock bodies and can be diaphragm or piston actuated. Many of the models are available in materials other than 316L so we welcome enquiries for valves made from exotics such as Hastelloy C, Monel, Alloy 20 etc. Valves can come with additional threaded ports for attaching inlet or outlet pressure gauges as well as features to make them tamper proof.
