Blanketing Valve 1088 CASHCO
The Model 1088 is a valve specifically designed for small tank blanketing applications. It opens and closes automatically as required, to maintain a closely controlled blanket pressure. Standard valve material provides added corrosion protection at no additional cost The simple design increases reliability and lowers maintenance cost.
Key Features
- Versatile: Single valve system offers wide variety of configurations to meet every blanketing application. Self cleaning flow design.
- Top Entry Design: Compact and light weight yet allows complete access to the valve internals without being removed from the tank. Only time the diaphragm case needs to be disassembled is when replacing the diaphragm.
- Stability: Pressure balanced pilot. Fluctuations in supply pressure does not affect set point
- Performance: Valve set point can be verified 100% on the tank, without removal and without flowing supply gas into the tank. Temperature changes have no appreciable effect on set point.
- Lower Maintenance Costs: Uses standard o-rings for seat and seals.

Applications:
On many low-pressure storage tanks the operating range is very low, which makes blanketing and venting system selection/design a challenge for the engineer. The Vacu-Gard® makes the job much easier. First, the Vacu-Gard® set point definition is where the blanketing valve closes bubble tight. This gives the largest dead band between the blanketing valve set point and the set point of the relieving device, and therefore will reduce losses. Second, the Vacu-Gard® has a wide range of available settings, from vacuum to 14 psig, that make proper selection easier.
