Piston Valves
Reliable, low-maintenance steam isolation

Piston Valves
Overview
Piston valves provide durable isolation and regulation, particularly on steam and condensate. Sealing rings around a precision piston give long-life, drip-tight shut-off with the ability to re-seal by simply tightening the gland.
Key Features
- Long-life sealing rings, drip-tight shut-off
- Ideal for steam and condensate
- Re-sealable by gland adjustment
- Robust, simple construction
- Low maintenance over long service life
Applications
Steam systems Condensate Heating Power General utilities
