Intermittent Blowdown Valve for Industrial Boiler – Precise Control, Reliable Protection
Our intermittent blowdown valve for industrial boiler delivers accurate, repeatable removal of suspended solids and dissolved minerals from boiler water. Designed for continuous‑duty power plants, process‑heat systems, and large‑scale heating networks, the valve integrates seamlessly with existing control panels and provides a proven method to maintain water chemistry within optimal limits.
How It Works – Simple, Automated, Safe
The valve operates on a timed‑pulse principle. When the boiler controller signals a blowdown event, the actuator opens the seat for a pre‑set duration (typically 5‑30 seconds). During this interval a measured volume of water is expelled, flushing out scale‑forming salts while preserving overall water inventory. After the pulse, the actuator returns to the closed position, eliminating the risk of over‑blowdown. Built‑in pressure‑feedback sensors verify that the set point is reached before each cycle, guaranteeing consistent performance even under fluctuating load conditions.
Competitive Advantages – What Sets Our Valve Apart
- Robust Construction: Body forged from ASTM A216 Gr. 91 carbon steel with a full‑length NPT‑type end‑connection, ensuring long‑term resistance to high‑temperature steam and corrosive condensate.
- Precision Timing: Adjustable electronic timer (0‑60 s) with ±0.5 s repeatability, eliminating manual adjustments and reducing operator error.
- Energy‑Efficient Design: Low‑torque pneumatic actuator (≤0.7 bar) reduces compressed‑air consumption and lowers plant operating costs.
- Easy Integration: 24 VDC control voltage, standard 4‑wire wiring, and ready‑made DIN‑rail module for plug‑and‑play installation.
- Safety‑First Features: Fail‑closed spring return, built‑in pressure relief, and compliance with IEC 60335‑2‑13 for safety in steam environments.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for a customized intermittent blowdown valve?
Our standard MOQ is 10 units for a fully customized configuration. For standard catalog models the MOQ can be reduced to a single unit, allowing rapid prototyping or spare‑part purchases.
Can the valve be adapted to different pressure classes?
Yes. The valve body and seat can be supplied in ASME B16.5 Class 150, 300, or 600 ratings. Adjustments are handled during the engineering phase, ensuring compliance with your plant’s design pressure.
What is the typical lead time after order confirmation?
Standard models ship within 15–25 days. Fully customized solutions, including special materials or extended timing ranges, require 30–45 days depending on engineering workload and material availability.
Is there a warranty or after‑sales support package?
All valves carry a 24‑month manufacturer warranty covering material and workmanship. Optional extended service contracts are available, providing on‑site calibration, spare‑part kits, and priority technical assistance.
