Home / Markets / WEAVALVES / Products / Valves / Valves Valves This category contains the different types of valves. These different types are Angle Seat, Ball, Butterfly, Check, Diaphragm, Globe, Manifold, Needle, Shuttle, Solenoid, and Zone Valves. Angle Seat Angle Seat Valves are linear motion on-off valves. They are pneumatic actuated, low cost, and compact. Applications vary greatly. Designed for special applications that require flow in both directions and incorporate an anti-water hammer design for liquid applications. Standard visual indicator shows open or closed position. Ball Ball Valves are quarter-turn ball valves available in manual, electric, or pneumatic actuators. The materials they are made from include brass, stainless steel, and plastic models. Applications include heating systems, water treatment, and gas or liquid flow control. Ball valves are available in a wide variety of sizes for versatile application. Butterfly Butterfly valves are quarter-turn butterfly valves available in manual, electric, and pneumatic actuators. There are steel and plastic models. Manual gear operators and SAE valves are available in the manual category. A few models have a cartridge seat design which alleviates installation problems. Check Check valves are back flow prevention valves. There are in-line and flap models. They are economical and used for both commercial and industrial application. A few models are designed with a smooth flow profile to minimize head loss and accumulation of debris. Diaphragm Pulse Diaphragm pulse valves are for controlling air pulses in dust collectors. A coupling connection allows for a quick and simple installation. Valves are offered in both integrated and remote coil configurations. Globe Globe valves are linear motion valves for flow control of gases, liquids, and steam. Models are pneumatic actuated and economical valves. Coupled with the high flow capacity, the Hi-Flow™ control valve maintains a wide rangeability of 50:1. A few models have metal-to-metal seating that ensures excellent flow control and shut-off service. Needle Needle valves are manual linear motion valves for precise flow control in low flow, small pipe applications. Models provide excellent performance and reliability. They have a tamper-proof design and blowout-proof stem. A few models are designed to be used in pressure or non-critical vacuum applications. Self Acting Temperature Control Self Acting Temperature Control valves are linear motion globe valves for flow control that has their own mechanical temperature sensors and temperature set points. No external power sources needed and this model is ideal for regulating the temperature of tanks, process streams, and various types of industrial equipment. Solenoid Solenoid valves are electric actuated on-off valves. They have a compact design. Some models are immune to mounting orientation. Compatible with a wide range of gases and liquids. Applications include flow control, water, process control, and chemical mixing. Zone Zone valves are electric actuated valves for flow control of hot and cold water in HVAC systems. Typically used in conjunction with a thermostat to control room temperature, models are either two or three way valves. Consult factory for 220 VAC power supply, optional auxiliary switches, and BSP or sweat connections. Manifold Manifold valves are manual block and bleed manifold valves for pressure instruments. Suited to control oil, water, toxic fluids, chemicals, air, and steam. Flanged models are designed to mount to an industrial differential pressure transmitter. Applications include oil refineries, nuclear power stations, petrochemical processing and more. Strainer Strainer valves provide excellent filtration to help prevent damage to valves, meters, etc. from rust and dirt, without sacrificing high flow characteristics. They are cost effective and high flow valves. Strainer valves have two options of materials: Brass and stainless steel. Manufactured for industrial applications.
