Valves with a thumb-screw handle open by rolling the slip-resistant thumb screw between your fingers. Since these valves don’t have a wide handle, they fit in tighter spaces than valves with other handle styles.

Inline handles can be operated from any position. The handle surrounds the drain outlet, so liquids may splash onto your hands or the handle.

Valves with a wing nut handle give you leverage to open tight, stubborn valves that have been sealed for long periods of time. The wings on these handles face inward, so they have a lower profile than handles with outlet-facing wing nuts.

Side handles are out of the way of the flow, so your hand and the handle stay dry.

Valves with a T-handle have two flat arms that provide more leverage and torque than thumb-screw handles and are more comfortable to grip than wing-nut handles. They have a removable handle, which can be disassembled for cleaning.

Breather vents with a plastic body are clear, so a quick glance will tell you if the gel is saturated. Unlike steel versions, which can be rebuilt, the entire unit must be replaced when fresh gel is needed.

For washdown environments, select breather vents with check valves. These valves allow air to flow in and out, but close when liquids try to enter.

For superior strength and reliability, choose 2205 stainless steel sights. All have a glass window that’s melted around a high-strength ring, so they won’t shatter, leak, or lose their shape under high pressure, heat, chemicals, or impact. They withstand harsh cleaners and sanitizers for clean-in-place (CIP) and steam-in-place (SIP) applications. USP Class VI and TUV Rheinland Certified, these sights meet safety standards in the U.S. and Europe. They also meet DIN standards for glass materials used in sights, ASTM standards for materials used in boilers and pressure vessels, and ASME BPE design standards for bioprocessing equipment that ensure purity and safety.
