SENTINEL Diaphragm Back Pressure Valves
Prevent siphoning and stabilize dosage rates with SENTINEL Diaphragm Back Pressure Valves
Diaphragm back pressure valves are designed to enhance the performance of pumping systems by applying a continuous back pressure to the system pump, while also acting as an anti-syphon valve. Robust construction ensures reliability in the rigorous service of municipal and industrial applications.
Reliability and low cost
Adjustable 5-150 psi for standard, 5-50 psi low pressure, or 50-350 psi high pressure
Anti-siphon function
Robust machined construction
Vulcanized PTFE/EPDM diaphragm
Full range of chemically resistant wetted materials
Sizes from ¼” to 4” depending on model
Diaphragm back pressure valves apply positive discharge pressure to a metering pump system to prevent siphoning and eliminate varying dosage rates caused by fluctuating downstream pressure. The diaphragm is held against the valve seat by an internal spring. When the preset pressure is exceeded, the diaphragm is forced up and system fluid flows through the valve to the injection point. The valves are preset for 50 psi, however they are field adjustable from 5 to 150 psi, (optional up to 350 psi for high pressure) via the adjustment screw. Installation should be as close to the injection point as possible to prevent system line drainage, and it is most important that all pumping system equipment such as pulsation dampeners and pressure gauges are between the pump and back pressure valve

Valve Hybride – Blacoh
l'avenir des systèmes de pompes doseuses. Présentation du premier amortisseur de pulsations combiné au monde et soupape de pression noire.
La nouvelle Hybrid Valve ™ de Blacoh, en attente de brevet, associe le contrôle constant du débit d'un amortisseur de pulsations et la régulation d'une vanne de contre-pression pour fournir les performances et les fonctionnalités des deux. Pourquoi installer et entretenir deux équipements lorsque le Hybrid Valve ™ fait la même chose, mais seulement mieux.
PERFORMANCE: LES CHIFFRES SONT INDÉNIABLE
La soupape hybride en instance de brevet a été conçue selon des principes éprouvés avec une conception de pointe pour des performances optimales et une efficacité maximale.
Dans un système de pompe doseuse, l'utilisation d'une soupape de contre-pression seule (orange) n'améliore en rien le débit de fluide. Lorsqu'il est mis en série avec un amortisseur de pulsations, le débit s'améliore de manière significative (rouge), mais les résultats ne peuvent toujours pas égaler les performances de la vanne hybride à construction unique pour le flux le plus stable (bleu).
Faites confiance aux experts en contrôle des fluides
L'emplacement et la proximité sont essentiels lors de l'installation d'amortisseurs de pulsations et de vannes de contre-pression dans tout système de pompage. Une soupape de surpression installée en série avec un amortisseur peut annuler l'effet d'amortissement si la soupape s'ouvre et se ferme avant que l'amortisseur ne puisse capter une impulsion complète. Cet effet d'ouverture rapide peut également générer trop de gain dans la soupape de contre-pression, ce qui entraîne une inefficacité et des bruits de claquement.
En combinant l’amortisseur et la soupape de surpression dans une seule unité technique, nous avons éliminé les problèmes les plus courants liés à l’installation pour un système plus efficace et simplifié.

Blacoh Hybrid Valve
The future of metering pump systems. Introducing the world's first combination pulsation dampener & back pressure valvve:
The new patent-pending Hybrid Valve™ from Blacoh combines the steady flow control of a pulsation dampener and the regulation of a back pressure valve to deliver the performance and functionality of both. Why install and maintain two pieces of equipment when the Hybrid Valve™ does the same- only better.
PERFORMANCE: THE NUMBERS ARE UNDENIABLE
The patent-pending Hybrid Valve was engineered to proven principles with state-of-the-art design for optimum performance and maximum efficiency.
In a metering pump system, using a back pressure valve alone (orange) does nothing to improve fluid flow. When put in series with a pulsation dampener, the flow improves significantly (red) but, results still can’t match the performance of the single construction Hybrid Valve for the steadiest flow (blue).
TRUST THE FLUID CONTROL EXPERTS
Location and proximity are key when installing pulsation dampeners and back pressure valves in any pumping system. A back pressure valve installed in series with a dampener can negate the dampening effect if the valve is opening and closing before the dampener is able to capture a full pulse. This quick-opening effect can also create too much gain within the back pressure valve resulting in inefficiency and chatter.
By combining the dampener and back pressure valve into a single engineered unit, we’ve eliminated the most common issues with installation for a more efficient, simplified system.
SEE THE HYBRID IN ACTION
Watch our Engineering Manager David McComb demonstrate the Hybrid Valve™ with a metering pump.
He will guide you through the performance of the pump with a pulsation dampener alone, then in series with a back pressure valve, and finally with the new Hybrid Valve™.
Understand the fluid dynamic principles to see why the Hybrid Valve™ delivers the best performance and giving your system the protection that it deserves.
