MISER No-Bleed Pilot Valve

Description

The MISER No-Bleed Pilot Valve is the most cost-effective solution for converting high-bleed pneumatic controls to low-bleed operation. This device effectively stops continuous bleed operation between dump cycles, thereby reducing environmentally concerning methane emissions, while allowing previously wasted gas to be sent to the sale line. Conservatively, users can anticipate 90% savings from recaptured gas based upon estimated cycle rates of the controls. 95-98% values may be achieved in some applications.

Features

• Cemco Cantilever Level Controls
• Cemco kits are field-installable in minutes –the unit does not have to be shut down for installation. Installation of pressure controller kits, although more in-depth, is still the most painless and cost-effective solution for converting high-bleed to low-bleed.
• Uses existing tubing and connections – no new plumbing required.
• MISER works in either snap-acting or throttling applications.
• 100% Made in the USA • Increased performance and eliminating leaking
• Highest Quality at the lowest price points
• Sold individually or with our snap heads
• 12 months of field testing before market

Method of Operation

Equilibrium Position: (Non-Venting Closed) When the MIZER® Pilot Valve is in a “Steady State”, both Seal “A” and Seal “B” are closed and the Control Flapper is in a neutral position. (See Fig. 1)

Depressed Position: (Non-Venting Actuating) When the Control Flapper depresses the Actuation Poppet, Seal “A” is opened, supplying gas to the process valve. Seal “B” is closed, preventing gas from bleeding or venting through the vent port. The MISER Pilot Valve is designed so that the gas flow is related to the position of the controller flap-per. (See Fig. 2)

Released Position: (Non-Continuous Venting) When the Control Flapper is released it closes Seal “A” and opens Seal “B” allowing gas to vent. Venting occurs ONLY when the control valve calls for it, and then, ONLY the gas in the process line and actuator is released. (See Fig. 3)
