Description
The Brodie BV70 differential control valve is a normally closed, regulating or positioning type valve designed for applications requiring valve closure on decreasing pressure differential such as pump differential pressure control and vapor pressure control for products with high flash points.
The valve does not require an outside power source to operate.
A controlled pressure differential is maintained within +/-2% regardless of variations in upstream or downstream pressure.
Features- Modular construction - all internal parts including seat ring can be removed with the cylinder assembly without disturbing line connections
- No diaphragms or stuffing boxes
- 45° body design assures high capacity
- Positive shut-off
- Uniform speed of response
- Linear control characteristics
- Inherently checks reverse flow
- O-Ring plus metal-metal seat
- Characterized ports for better low flow response
